cf845297d5 [media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHz
Currently, the driver assumes that all QAM carriers are spaced with
8MHz. This is wrong, and may decrease QoS on Countries like Brazil,
that have DVB-C carriers with 6MHz-spaced.

Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to
associate the symbol rate with the bandwidth needed for it.

For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.15 = 5217391 Bauds
For  ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.13 = 5309735 Bauds.

As this tuner is currently used only for DRX-K, and it is currently
hard-coded to annex A, I've opted to use the roll-off factor of 0.15,
instead of 0.13.

If we ever support annex C, the better would be to add a DVB S2API
call to allow changing between Annex A and C, and add the 0.13 roll-off
factor to it.

This code is currently being used on other frontends, so I think we
should later add a core function with this code, to warrant that
it will be properly implemented everywhere.

d749fb663e [media] au8522: set signal field to 100% when signal present
The signal state field in G_TUNER is typically scaled from 0-100%.  Since we
don't know the signal level, we really would prefer the field to contain 100%
than 1/256, which in many utilities (such as v4l2-ctl) rounds to 0% even when
a signal is actually present.

This patch makes the behavior consistent with other drivers.

320ed23ebf [media] drxk: Fix a bug at some switches that broke DVB-T
The error propagation changeset c23bf4402 broke the DVB-T
code.

The legacy way for propagate errors was:

do {
	status = foo_func()
	if (status < 0)
		break;
} while (0);
return status;

However, on a few places, it was doing:
do {
	switch(foo) {
	case bar:
		status = foo_func()
		if (status < 0)
			break;
		break;
	}
	switch(foo2) {
	case bar:
		status = foo_func()
		if (status < 0)
			break;
		break;
	}
	...
} while (0);
return (status)

The inner error break were not working, as it were breaking only
the switch, instead of the do. The solution used were to do a
s/break/goto error/ at the inner breaks, but preserving the last
break. Onfortunately, on a few switches, the replacement were
applied also to the final break for the case statements.

Fix the broken logic, by reverting them to break, where pertinent,
in order to fix DVB-T support.

c4c3a3d32a [media] Remove the double symbol increment hack from drxk_hard
Both ngene and ddbrige calls dvb_attach once for drxk_attach.
The logic used there, and by tda18271c2dd driver is different
from similar logic on other frontends.

The right fix is to change them to use the same logic, but,
while we don't do that, we need to patch em28xx-dvb in order
to do cope with ngene/ddbridge magic.

While here, document why drxk_t_release should do nothing.

As pointed by Andread Oberritter <obi@linuxtv.org>:

	That's wrong, because the array size is DTV_MAX_COMMAND + 1.
	Using the ARRAY_SIZE macro instead might reduce the confusion.

Also, changeset 3995223038 already fixed this issue.

8afe9119e2 [media] media, Micronas dvb-t: Fix mem leaks, don't needlessly zero mem, fix spelling
In drivers/media/dvb/frontends/drxd_hard.c::load_firmware() I see 3
small issues:

 1) When the 'fw' variable goes out of scope we'll leak the memory
 allocated to it by request_firmware() by neglecting to call
 release_firmware().

 2) After a successful request_firmware() we allocate fw->size bytes
 of memory using kzalloc() only to immediately overwrite all that
 memory with memcpy(), so asking for zeroed memory seems like wasted
 effort - just use kmalloc().

 3) In one of the error messages "no memory" lacks a space and is
 written as "nomemory".

This patch fixes all 3 issues.

5eee2bb270 [media] drxk: Add a fallback method for QAM parameter setting
The QAM standard is set using this scu_command:
	SCU_RAM_COMMAND_STANDARD_QAM |
	SCU_RAM_COMMAND_CMD_DEMOD_SET_PARAM

The driver implements a version that has 4 parameters, however,
Terratec H5 needs to break this into two separate commands, otherwise,
DVB-C doesn't work.

With this fix, scan is now properly working and getting the
channel list:
>>> tune to: 609000000:INVERSION_AUTO:5217000:FEC_3_4:QAM_256
>>> tuning status == 0x00

7558977a4a [media] drxk: Improve the scu_command error message

Better than ERROR -3. This happens with Terratec H5 firmware.

It adds 2 new error conditions, and something useful to track
what the heck is that.

I suspect that the scu_command is dependent on the firmware
revision.

90796acad0 [media] drxk: Improves the UIO handling
The driver is too limited: it assumes that UIO is used only for
controlling the antenna, and that only UIO-1 is in usage. However,
from Terratec H7 driver [1], 3 UIO's can be used. In fact, it seems
that H7 needs to use all 3. So, make the code generic enough to handle
the most complex scenario. For now, only antena GPIO can be specified,
but is is easier now to add the other GPIO/UIO needs.

be44eb283b [media] drxk: Proper handle/propagate the error codes
This driver is very big and complex. An error happening in the middle
of any initialization may cause the frontend to not work. So, it
needs to properly propagate error codes internally and to userspace.

Also, printing the error codes at the places it happened helps to
discover were's a bug at the code.

Before this change, a do { } while (0) loop and lots of breaks inside
were used to propagate errors. While this works, if there are
loops inside other loops, it could be easy to forget to add another
break, causing the error to not abort the function.

Also, as not all functions were reporting errors, it is hard to
discover why something failed.

5e66b87840 [media] drxk: remove _0 from read/write routines
The normal 16-bits read routine is called as "Read16_0". This is

The same happens with 16-bits write and 32-read/write routines,
and with WriteBlock.

Also, using flags, is an exception: there's no place currently using
flags, except for an #ifdef at WriteBlock.

Rename the function as just "read16", and the one that requires flags,
as "read16_flags".

This helps to see where the flags are used, and also avoid using
CamelCase on Kernel.

1bd09ddcff [media] drxk: fix warning: ‘status’ may be used uninitialized in this function
One of the problems of the old CHECK_ERROR is that it was hiding
the status parameter. Maybe due to that, on a few places, the return
code might lead to return incorrect status:

drivers/media/dvb/frontends/drxk_hard.c: In function ‘load_microcode.clone.0’:
drivers/media/dvb/frontends/drxk_hard.c:1281: warning: ‘status’ may be used uninitialized in this function

469ffe0836 [media] tda18271c2dd: Remove the CHK_ERROR macro
The CHK_ERROR macro does a flow control, violating chapter 12
of the Documentation/CodingStyle. Doing flow controls inside
macros is a bad idea, as it hides what's happening. It also
hides the var "status" with is also a bad idea.

The changes were done by this small perl script:
	my $blk=0;
	while (<>) {
		s/^\s+// if ($blk);
		$f =~ s/\s+$// if ($blk && /^\(/);
		$blk = 1 if (!m/\#/ && m/CHK_ERROR/);
		$blk=0 if ($blk && m/\;/);
		s/\n/ / if ($blk);
		$f.=$_;
	};
	$f=~ s,\n(\t+)CHK_ERROR\((.*)\)\;([^\n]*),\n\1status = \2;\3\n\1if (status < 0)\n\1\tbreak;,g;

	print $f;

And manually fixed.
