2011-08-27[media] cx88: notch filter control fixesistvan_v@mailbox.hu
This patch reduces the number of available choices for the notch filter type control so that the standard-specific filter types cannot be selected. It is now limited to being either 0 (4xFsc, the default) or 1 (square pixel optimized). The patch also removes the initialization of this control from cx88_reset(), since that is already done by init_controls(), which is called by cx8800_initdev().

2011-07-27[media] Stop using linux/version.h on most video driversMauro Carvalho Chehab
All the modified drivers didn't have any version increment since Jan, 1 2011. Several of them didn't have any version increment for a long time, even having new features and important bug fixes happening. As we're now filling the QUERYCAP version with the current Kernel Release, we don't need to maintain a per-driver version control anymore. So, let's just use the default. In order to preserve the Kernel module version history, a KERNEL_VERSION() macro were added to all modified drivers, and the extraver number were incremented. I opted to preserve the per-driver version control to a few pwc, pvrusb2, s2255, s5p-fimc and sh_vou. A few drivers are still using the legacy way to handle ioctl's. So, we can't do such change on them, otherwise, they'll break. Those are: uvc, et61x251 and sn9c102. The rationale is that the per-driver version control seems to be actively maintained on those. Yet, I think that the better for them would be to just use the default version numbering, instead of doing that by themselves. While here, removed a few uneeded include linux/version.h Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Upcoming I2C v4l2_subdev drivers need a way to control the subdevice power state from the core. This use case is already partially covered by the tuner s_standby operation, but no way to explicitly come back from the standby state is available. Rename the tuner s_standby operation to core s_power, and fix tuner drivers accordingly. The tuner core will call s_power(0) instead of s_standby(). No explicit call to s_power(1) is required for tuners as they are supposed to wake up from standby automatically.
