8d4eb2acb6 [media] mtk-vcodec: fix default OUTPUT buffer size
When calculate OUTPUT buffer size in vidioc_try_fmt, it will
add more size hw need in each plane.
But in mtk_vcodec_enc_set_default_params, it do not add
same size in each plane.
This makes v4l2-compliance test fail.
This patch fix the issue.

19e476c7b0 [media] mtk-vcodec: fix more type mismatches
The newly added mtk-vcodec driver produces a number of warnings in an
ARM allmodconfig build, mainly since it assumes that dma_addr_t is
32-bit wide:

mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

This rearranges the format strings and type casts to what they should
have been in order to avoid the warnings. e0f80d8d62 ("[media]
mtk-vcodec: fix two compiler warnings") fixed some of the problems that
were introduced at the same time, but missed two others.

9e422f64fa [media] af9035: fix dual tuner detection with PCTV 79e
The value 5 of the EEPROM_TS_MODE register (meaning dual tuner presence) is
only valid for AF9035 devices. For IT9135 devices it is invalid and led to a
false positive dual tuner mode detection with PCTV 79e.
Therefore on non-AF9035 devices and with value 5 the driver now defaults to
single tuner mode and outputs a regarding info message to log.

This fixes Bugzilla bug #118561.

5cac1f67ea [media] rc: nuvoton: fix hang if chip is configured for alternative EFM IO address
If a system configures the Nuvoton chip to use the alternative
EFM IO address (CR_EFIR2) then after probing the primary EFM IO
address (CR_EFIR) this region is not released.

If a driver for another function of the Nuvoton Super I/O
chip uses the same probing mechanism then it will hang if
loaded after the nuvoton-cir driver.
This was reported for the nct6775 hwmon driver.

Fix this by properly releasing the region after probing CR_EFIR.
This regression was introduced with kernel 4.6 so cc it to stable.

fe35637b0a [media] dvb_frontend: eliminate blocking wait in dvb_unregister_frontend()
The wait_event() call in dvb_unregister_frontend() waits synchronously
for other tasks to free a file descriptor, but it does that while
holding several mutexes.  That alone is a bad idea, but if one user
process happens to keep a (defunct) file descriptor open indefinitely,
the kernel will correctly detect a hung task:

    INFO: task kworker/0:1:314 blocked for more than 30 seconds.
          Not tainted 4.7.0-rc1-hosting+ #50

 - set_use_inc() when opening the device

if those are not set by the lirc user, the system segfaults.

199946731f [media] vsp1: clarify FCP dependency
The newly added FCP support in the vsp1 driver causes a link error

drivers/media/built-in.o: In function `vsp1_remove':

drivers/media/built-in.o: In function `vsp1_probe':
:(.text+0xdef44): undefined reference to `rcar_fcp_get'

We already have a conditional dependency on FCP that requires
it for ARM64, so for all others we just have to prevent setting
RENESAS_VSP1=y when RENESAS_FCP=m by extending the FCP dependency.

fb66852d4c [media] tw686x: use a formula instead of two tables for div
Instead of using two tables to estimate the temporal decimation
factor, use a formula. This allows to get the closest fps, which
sounds better than the current tables.

Also, the current code doesn't store the real framerate.

This patch fixes the above issues.

[Ezequiel:
  - introduce a TW686X_MAX_FPS macro for max_fps.
  - use hweight_long instead of open coding the set bits count.]

My static checker complains that if adap->props.num_frontends is 0 then
"ret" is uninitialized.  I don't think that can happen.  But "ret" is

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.

fd74246d2a [media] adv7604/adv7842: fix quantization range handling
Fix a number of bugs that appeared when support for mediabus formats was
added:

- Support for V4L2_DV_RGB_RANGE_FULL/LIMITED should only be enabled
  for HDMI RGB formats, not for YCbCr formats. Since, as the name
  says, this setting is for RGB only. So read the InfoFrame to check
  the format.

- the quantization range for the pixelport depends on whether the
  mediabus code is RGB or not: if it is RGB, then produce full range
  RGB values, otherwise produce limited range YCbCr values.

  This means that the op_656_range and alt_data_sat fields of the
  platform data are no longer used and these will be removed in a
  following patch.

- when setting up a new format the RGB quantization range settings
  were never updated. Do so, since this depends on the format.

- fix the log_status output which was confusing and incorrect.

0a25a01251 [media] adv7511: fix quantization range handling
Commit 1fb69bfd29 (adv7511: improve
colorspace handling) introduced a number of bugs, specifically with
regards to YCbCr output and quantization range handling:

- if the output is not RGB, then disable the full-to-limited range
  CSC matrix since that is meant for RGB formats. YCbCr formats are
  always limited range, so there is nothing to convert. (OK, full
  range YCbCr is possible, but we don't support that right now).

- the mediabus code that was passed to adv7511_set_fmt was always cleared
  by the memset in adv7511_fill_format. This made it effectively impossible
  to select YCbCr output.

- adv7511_set_fmt never updated the rgb quantization range.

2a00932f08 [media] media: usbtv: prevent access to free'd resources
When disconnecting the usbtv device, the sound card is unregistered
from ALSA and the snd member of the usbtv struct is set to NULL.  If
the usbtv snd_trigger work is running, this can cause a race condition
where the kernel will attempt to access free'd resources, shown in
[1].

This patch fixes the disconnection code by cancelling any snd_trigger
work before unregistering the sound card from ALSA and checking that
the snd member still exists in the work function.
