Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.
The patch was generated via the script below, and manually
adjusted if needed.
</script>

$c=$_;
if ($c =~ /^\s+\"(.*)/) {

$s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2;

Kernel source files need not include <linux/kconfig.h> explicitly

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.

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

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.

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.

C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

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.

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.

Use a linear interpolation to make it look better.

Instead of using a relative frequency range, calibrate it to
show the results in dB. The callibration was done getting

incremented in steps of 0.5 dB, using 3 frequencies:
175 MHz, 410 MHz and 800 MHz. The modulated signal was
using QAM64, and it was used a linear interpolation of all

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.

Pull i2c updates from Wolfram Sang:
- Peter Rosin did some major rework on the locking of i2c muxes by
seperating parent-locked muxes and mux-locked muxes.
This avoids deadlocks/workarounds when the mux itself needs i2c
commands for muxing. And as a side-effect, other workarounds in the
media layer could be eliminated. Also, Peter stepped up as the i2c
mux maintainer and will keep an eye on these changes.
- major updates to the octeon driver
- add a helper to the core to generate the address+rw_bit octal and
make drivers use it
- quite a bunch of driver updates

Using div_u64() instead of do_div() makes the code slightly more
readable by humans.
[mchehab@osg.samsung.org: originally, this patch was proposed as a bug
fix for a gcc bug. This was solved already, but it is still better to
use div_u64, instead of do_div, so I'm applying it, removing the
comments about the gcc bug]

The root i2c adapter lock is then no longer held by the i2c mux during
accesses behind the i2c gate, and such accesses need to take that lock
just like any other ordinary i2c accesses do.
So, declare the i2c gate mux-locked, and zap the regmap overrides
that makes the i2c accesses unlocked and use plain old regmap
accesses. This also removes the need for the regmap wrappers used by
rtl2832_sdr, so deconvolute the code further and provide the regmap
handle directly instead of the wrapper functions.

s32tmp in the below code may be negative, and dev->mclk_khz is an
unsigned type.
s32tmp = 0x10000 * (tuner_frequency - c->frequency);
s32tmp = DIV_ROUND_CLOSEST(s32tmp, dev->mclk_khz);
This is undefined, as DIV_ROUND_CLOSEST is undefined for negative
dividends when the divisor is of unsigned type.
So, change mclk_khz to be signed (s32).

Change get_frontend to re-check current lock status rather than relying
on a cached value from get_status. Removes potential for tuning failure
if get_frontend is called during tuning.
Probably not too essential as other changes work around this:
