V4L/DVB (11661): v4l2-ioctl: Check buffer types using g_fmt instead of try_fmt
For a number of different ioctls, the v4l2-ioctl code checks that the passed buffer type is supported by the driver. It did this by checking that the driver defined a method for the try_fmt handler for that buffer type. However, try_fmt is optional and a driver might not provide it even though it does support that type. So use g_fmt instead, since that isn't optional. This should fix a problem with VBI capture with saa7146. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
