V4L/DVB (5886): zr36067: Fix problem setting norms
The zr36067 driver doesn't make a distinction between the different sub-types of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I. When setting the norm, it required the bitmask to match exactly the set of norms used during the enumeration. If just one norm was specified, for example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec, "VIDIOC_S_STD accepts *one* or more flags..." The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple bits. It's ok to call S_STD with any *one* of those bits, but the driver was requiring *all* of them. This fixes the S_STD function so that it will accept any set of one or more PAL norms as PAL, and the same for NTSC and SECAM. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Ronald S.
