97139d4a6f treewide: remove redundant #include <linux/kconfig.h>
Kernel source files need not include <linux/kconfig.h> explicitly
because the top Makefile forces to include it with:

  -include $(srctree)/include/linux/kconfig.h

This commit removes explicit includes except the following:

  * arch/s390/include/asm/facilities_src.h
  * tools/testing/radix-tree/linux/kernel.h

These two are used for host programs.

2df9dda07f [media] si2165: avoid division by zero
When si2165_init fails, the clk values in state are still at zero.
But the dvb-core ignores the return value of init will call tune
afterwards.
This will trigger a division by zero when tuning.
At least check for the variables to be non-zero before dividing.

This happened for a system with WinTV HVR-4400 PCIe-card after suspend-to-disk.
Do suspend-to-disk without accessing the DVB device before.
After wakeup try to tune.
si2165_init fails at checking the chip_mode and aborts.
Then si2165_set_if_freq_shift will fail with div-by-zero.

505a0ea706 [media] mb86a20s: fix demod settings
With the current settings, only one channel locks properly.
That's likely because, when this driver was written, Brazil
were still using experimental transmissions.

Change it to reproduce the settings used by the newer drivers.
That makes it lock on other channels.

Tested with both PixelView SBTVD Hybrid (cx231xx-based) and
C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

dafb65fb98 [media] mb86a20s: fix the locking logic
On this frontend, it takes a while to start output normal
TS data. That only happens on state S9. On S8, the TS output
is enabled, but it is not reliable enough.

However, the zigzag loop is too fast to let it sync.

As, on practical tests, the zigzag software loop doesn't
seem to be helping, but just slowing down the tuning, let's
switch to hardware algorithm, as the tuners used on such
devices are capable of work with frequency drifts without
any help from software.

bb9bd87808 drivers/media/dvb-frontends/cxd2841er.c: avoid misleading gcc warning
The addition of jump label support in dynamic_debug caused an unexpected
warning in exactly one file in the kernel:

  drivers/media/dvb-frontends/cxd2841er.c: In function 'cxd2841er_tune_tc':
  include/linux/dynamic_debug.h:134:3: error: 'carrier_offset' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     __dynamic_dev_dbg(&descriptor, dev, fmt, \
     ^~~~~~~~~~~~~~~~~
  drivers/media/dvb-frontends/cxd2841er.c:3177:11: note: 'carrier_offset' was declared here
    int ret, carrier_offset;
             ^~~~~~~~~~~~~~

The problem seems to be that the compiler gets confused by the extra
conditionals in static_branch_unlikely, to the point where it can no
longer keep track of which branches have already been taken, and it
doesn't realize that this variable is now always initialized when it
gets used.

I have done lots of randconfig kernel builds and could not find any
other file with this behavior, so I assume it's a rare enough glitch
that we don't need to change the jump label support but instead just
work around the warning in the driver.

To achieve that, I'm moving the check for the return value into the
switch() statement, which is an obvious transformation, but is enough to
un-confuse the compiler here.  The resulting code is not as nice to
read, but at least we retain the behavior of warning if it gets changed
to actually access an uninitialized carrier offset value in the future.

cd82982179 [media] ascot2e: Fix I2C message size check
Tuning a card with Sony ASCOT2E produces the following error:

	kernel: i2c i2c-9: wr reg=0006: len=11 is too big!

MAX_WRITE_REGSIZE is defined as 10, buf[MAX_WRITE_REGSIZE + 1] buffer is
used in ascot2e_write_regs().

The problem is that exactly 10 bytes are written in ascot2e_set_params():

	/* Set BW_OFFSET (0x0F) value from parameter table */
	data[9] = ascot2e_sett[tv_system].bw_offset;
	ascot2e_write_regs(priv, 0x06, data, 10);

The test in write_regs is as follows:

	if (len + 1 >= sizeof(buf))

10 + 1 = 11 and that would be exactly the size of buf. Since 10 bytes +
buf[0] = reg would seem to fit into buf[], this shouldn't be an error.
