Don't allow sleep when getting the gpio value in the irq-handler.
On my rk3288 board this results in might_sleep warnings when receiving
data like:

9056a23ba1 [media] dvb-frontend: Replace timeval with ktime_t
struct timeval uses a 32-bit seconds representation which will
overflow in the year 2038 and beyond. This patch replaces
the usage of struct timeval with ktime_t which is a 64-bit
timestamp and is year 2038 safe.
This patch is part of a larger attempt to remove all instances
of 32-bit timekeeping variables (timeval, timespec, time_t)
which are not year 2038 safe, from the kernel.

d3525b632a [media] b2c2: Add option to skip the first 6 pid filters
The flexcop bridge chip has two banks of hardware pid filters -
an initial 6, and on some chip revisions an additional bank of 32.

A bug is present on the initial 6 - when changing transponders
one of two PAT packets from the old transponder would be included
in the initial packets from the new transponder. This usually
transpired with userspace programs complaining about services
missing, because they are seeing a PAT that they would not be
expecting. Running in full TS mode does not exhibit this problem,
neither does using just the additional 32.

This patch adds in an option to not use the inital 6 and solely use
just the additional 32, and enables this option for the SkystarS2
card. Other cards can be added as required if they also have
this bug.

25e057fdde [media] ddbridge: Do not free_irq() if request_irq() failed
My static checker detected that free_irq() is called even after
request_irq() failed in ddb_probe(). In this case, the kernel may try to
free dev->pdev->irq although the IRQ is not assigned. This event rarely
occurs, but always introduces a warning if it happens.

"goto fail1" always results in disabling enabled MSI and releasing a
requested IRQ. It seems like the former handling is necessary. So I added
a conditional branch before the free_irq() (stat == 0 means request_irq()
succeeds).

'struct timeval last_tv' is used to get the time of last signal change
and 'struct timeval last_intr_tv' is used to get the time of last UART

32-bit systems using 'struct timeval' will break in the year 2038, so we
have to replace that code with more appropriate types.
Here struct timeval is replaced with ktime_t.

7f3c2e1d1d [media] cx231xx: fix compiler warning
Fix this compiler warning by allocating a structure to read the eeprom instead
of doing it on the stack and worse: the eeprom array is static, so that can
cause problems if there are multiple cx231xx instances.

cx231xx-cards.c: In function 'cx231xx_card_setup':
cx231xx-cards.c:1110:1: warning: the frame size of 2064 bytes is larger than 2048 bytes [-Wframe-larger-than=]
 }
 ^

I did consider removing the code altogether since the result is actually
not used at the moment, but I decided against it since it is used in other
drivers and someone might want to start using it in this driver as well. And
then it is useful that the code is already there.

061ddda681 [media] v4l2-dv-timings: add interlace support in detect cvt/gtf
Extend detect_cvt/gtf API to indicate the format type (interlaced
or progressive). In case of interlaced, the vertical front and back
porch and vsync values for both (odd,even) fields are considered to
derive image height. Populated vsync, vertical front, back porch
values in bt timing structure for even and odd fields and updated
the flags appropriately.

Also modified the functions calling the detect_cvt/gtf(). As of now
these functions are calling detect_cvt/gtf() with interlaced flag
set to false.

8cf6874e84 [media] v4l2-dv-timings: support interlaced in v4l2_print_dv_timings
The v4l2_print_dv_timings() didn't log the interlaced format correctly. The timings
for the bottom field weren't logged and the fields per second value was half of what
it should have been.

dc0cf4cfed [media] v4l2-dv-timing: avoid rounding twice in gtf hblank calc
Currently, in gtf hblank calculations, the rounding is used twice,
one at intermediate division and one at final state where hblank
is rounded to nearest multiple of twice cell granularity. This
error got introduced in 'commit d7ed5a3dda ("[media]
v4l2-dv-timings: fix rounding in hblank and hsync calculation"),
where it missed combining the rounding step. Correcting the same
in this patch.
