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. Signed-off-by:Mauro Carvalho Chehab <mchehab@redhat.com>

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. Signed-off-by: -

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. Reported-by:

[media] em28xx: save isoc endpoint number for DVB only if endpoint has alt settings with xMaxPacketSize != 0 X-Patchwork-Delegate: mchehab@redhat.com In addition to commit 72cc9ba3 "em28xx: ignore isoc DVB USB endpoints with wMaxPacketSize = 0 bytes for all alt settings" we should not save the endpoint number of the isoc DVB endpoint before it has been validated. While the current code works fine, dev->dvb_ep_isoc != 0 could be interpreted as indicator that the device provides DVB support. Signed-off-by:

Originally struct v4l2_capability driver and card name was filled with name of the platform device. After switching to the device tree the device names have changed and now are 4 different driver names reported, depending on the video device opened. So instead of e.g. "exynos4-fimc" there is now one of: 11800000.fimc, 11810000.fimc, 11820000.fimc, 11830000.fimc. Fix this by using dev->driver_name, rather than platform device name. A common vidioc_querycap function is created for both M2M and capture video node. This fixes any breakage at user space should any application/library rely on the driver's name. Signed-off-by:
