When 'node' is NULL, the print statement tries to dereference it.
Hence replace the variable with the one that is accessible.

For NV12 format, even if display data is single image,
both VIDWIN0 and VIDWIN1 parameters must be used. The start
address of Y data plane and C data plane is configured in
VIDEOWIN0ADH/L and VIDEOWIN1ADH/L respectively.
cuurently only one layer was requested, which is suffice
for yuv422, but for yuv420(NV12) two layers are required and
fix the same by requesting for other layer if pix fmt is NV12
during set_fmt.

Along the time, several debug messages were added at cx88-cards.
While those are still useful to track some troubles with
tuners, they're too verbose:
[ 5768.281801] cx88[0]: Calling XC2028/3028 callback
[ 5768.287388] cx88[0]: Calling XC2028/3028 callback

[ 5768.306244] cx88[0]: Calling XC2028/3028 callback
...
and, most of the time, useless.
So, disable them, except if core_debug modprobe parameter
is used.

I think we could just move the full vm_iomap_memory() function into
util.h or similar, but I didn't get any reply from anybody actually
using nommu even to this trivial patch, so I'm not going to touch it any

Here's the fairly minimal stub to make the nommu case at least

variable_is_present() accesses '__efivars' directly, but when called via
gsmi_init() Michel reports observing the following crash,
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: variable_is_present+0x55/0x170
Call Trace:
register_efivars+0x106/0x370
gsmi_init+0x2ad/0x3da
do_one_initcall+0x3f/0x170
The reason for the crash is that '__efivars' hasn't been initialised nor
has it been registered with register_efivars() by the time the google
EFI SMI driver runs. The gsmi code uses its own struct efivars, and
therefore, a different variable list. Fix the above crash by passing
the registered struct efivars to variable_is_present(), so that we
traverse the correct list.

we removed timestamps from tty inodes to fix a security issue and waited
if something breaks. Well, 'w', the utility to find out logged users

User applications running on SMP kernels have long suffered from instability
and random segmentation faults. This patch improves the situation although
there is more work to be done.
One of the problems is the various routines in pgtable.h that update page table
entries use different locking mechanisms, or no lock at all (set_pte_at). This
change modifies the routines to all use the same lock pa_dbit_lock. This lock
is used for dirty bit updates in the interruption code. The patch also purges
the TLB entries associated with the PTE to ensure that inconsistent values are
not used after the page table entry is updated. The UP and SMP code are now
identical.
The change also includes a minor update to the purge_tlb_entries function in
cache.c to improve its efficiency.

CONFIG_MLONGCALLS was introduced in commit
ec758f98328da3eb933a25dc7a2eed01ef44d849 to overcome linker issues when linking
huge linux kernels, e.g. with many modules linked in.
But in the kernel module loader there is no support yet for the new relocation
types, which is why modules built with -mlong-calls can't be loaded.
Furthermore, for modules long calls are not really necessary, since we already
use stub sections which resolve long distance calls.
So, let's just disable this compiler option when compiling kernel modules.

When targetting 32-bit processors, __put_user emits a pair of stw
instructions for the 8-byte case. If the type of __val is a pointer, the
marshalling code casts it to the wider integer type of u64, resulting
in the following compiler warnings:
kernel/signal.c: In function 'copy_siginfo_to_user':
kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
[...]
This patch fixes the warnings by removing the marshalling code and using
the correct output modifiers in the __put_{user,kernel}_asm64 macros
so that GCC will allocate the right registers without the need to
extract the two words explicitly.

The 'help' section of the Kconfig entry for this driver is missing
an extra alignment. That seems to violate what's stated at:
Documentation/kbuild/kconfig-language.txt
Even if it works, the better is to add 2 extra spaces there, as
this is the common practice and helps human reading of the file.
Also, the way it is, it breaks backport trees.

The hole reason for __must_check is to not ignore an error.
However, a "ret" value is used at cx25821 just to avoid the
Kernel compilation to compain about it.
That, however, produces another warning (with W=1):
drivers/media/pci/cx25821/cx25821-alsa.c: In function 'cx25821_audio_fini':
drivers/media/pci/cx25821/cx25821-alsa.c:727:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]
With the current implementation of driver_for_each_device() and
cx25821_alsa_exit_callback(), there's actually just one
very unlikely condition where it will currently produce
an error: if driver_find() returns NULL.
Ok, there's not much that can be done, as it is on a driver's
function that returns void, but it can at least print some message
if the error happens.

After cx25821-video cleanup, this var is not used anymore:
drivers/media/pci/cx25821/cx25821-video.c: In function 'cx25821_vidioc_try_fmt_vid_cap':
drivers/media/pci/cx25821/cx25821-video.c:591:15: warning: variable 'maxw' set but not used [-Wunused-but-set-variable]
as the code now checks the max width as the default case for the
range check.

Currently, the driver complains about the pre_detect var:
drivers/media/tuners/r820t.c: In function 'r820t_sysfreq_sel':
drivers/media/tuners/r820t.c:722:31: warning: variable 'pre_dect' set but not used [-Wunused-but-set-variable]
While rtl8232 code comments it, perhaps some other driver may use.
So, the better is to keep the code there, allowing to enable it
via r820t config data.

The check if the values for c, h and n are within the range is
always true, as, if one of this values is out of range, the
previous "if" clauses will default to a value within the
range.
That fixes the following warning:
drivers/media/dvb-frontends/dib0090.c: In function 'dib0090_set_EFUSE':
drivers/media/dvb-frontends/dib0090.c:1545:5: warning: comparison is always true due to limited range of data type [-Wtype-limits]
and makes the code easier to read.

isdbt_sb_subchannel is unsigned with 8 bits. So, it will
never be -1. Instead, any value bigger than 13 is invalid.
As is, the current code generates the following warnings:
drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_set_isdbt_common_channel':
drivers/media/dvb-frontends/dib8000.c:2358:3: warning: comparison is always true due to limited range of data type [-Wtype-limits]
drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_tune':
drivers/media/dvb-frontends/dib8000.c:3107:8: warning: comparison is always false due to limited range of data type [-Wtype-limits]
drivers/media/dvb-frontends/dib8000.c:3153:9: warning: comparison is always false due to limited range of data type [-Wtype-limits]
drivers/media/dvb-frontends/dib8000.c:3160:5: warning: comparison is always false
It should also be noticed that ARIB STD-B31, item
"3.15.6.8 Number of segments" at TMCC table defines the
value 15 for unused segment, and 14 as reserved.
So, better to change the check to consider any value
bigger than 13 to mean that sub-channels should be
disabled, fixing the warning and doing the right thing
even if an invalid value is filled by userspace.

dtv_property_cache is used on several places on very long lines.
On all places it is used, a long list of struct reference is done.
Instead of doing it, at the routines where it is used more than once,
replace it by one temporary var. That may help the compiler to
use a better code. It also makes easier to review the code, as the
lines becomes closer to 80 columns, making them a way clearer
to read.
No functional changes.

Memory maps typically require that the buffer size to be page
aligned. Currently, two memops drivers do such alignment
internally, but videobuf-vmalloc doesn't.
Also, the buffer overflow check doesn't take it into account.
So, instead of doing it at each memops driver, enforce it at
VB2 core.
