      V4L/DVB (10559): bttv: Fix TDA9880 norm setting code · 72134a6d
      由 Trent Piepho 提交于 
      The code to set the norm for the TDA9880 analog demod was comparing
btv->norm, an index into the bttv driver's norm array, to V4L2_STD_NTSC,
which is a bit flag that's part of the V4L2 API.  This doesn't work of
course and results in the PAL path always being taken.

What's more, it modified the bttv_tvcards[] entries for cards using the
TDA9880.  This is wrong because changing the norm on one card will also
affect other cards of the same type.  Writing to bttv_tvcards is also bad
because it should be read-only or even devinitdata.

Changing the norm would also cause the audio to become unmuted.

Have the code get called for both norm setting and audio input setting
(which where the gpios are set) to avoid needed to modify bttv_tvcards.

      V4L/DVB (10558): bttv: norm value should be unsigned · 4ef2ccc2
      由 Trent Piepho 提交于 
      The norm value in the driver is an index into an array and the the driver
doesn't allow it to be negative or otherwise invalid.  It should be
unsigned but wasn't in all places.

Fix some structs and functions to have the norm be unsigned.  Get rid of
useless checks for "< 0".  Most of the driver code can't handle a norm
value that's out of range, so change some ">= BTTV_TVNORMS" checks to
BUG_ON().  There's no point in silently ignoring invalid driver state just
to crash because of it later.

      V4L/DVB (9327): v4l: use video_device.num instead of minor in video%d · c6330fb8
      由 Hans Verkuil 提交于 
      The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now
independent of the minor number. So instead of using the minor field
of the video_device struct one has to use the num field: this always
contains the kernel number of the device node.

I forgot about this when I did the v4l2 core change, so this patch
converts all drivers that use it in one go. Luckily the change is
trivial.

      V4L/DVB (8955): bttv: Prevent NULL pointer dereference in radio_open · c37396c1
      由 Jean Delvare 提交于 
      Fix the following crash in the bttv driver:

BUG: unable to handle kernel NULL pointer dereference at 000000000000036c
IP: [<ffffffffa037860a>] radio_open+0x3a/0x170 [bttv]

This happens because radio_open assumes that all present bttv devices
have a radio function. If a bttv device without radio and one with
radio are installed on the same system, and the one without radio is
registered first, then radio_open checks for the radio device number
of a bttv device that has no radio function, and this breaks. All we
have to do to fix it is to skip bttv devices without a radio function.
