From c6b69c6c58288587c33efb43ca6e19f1c80b2757 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Sun, 19 Aug 2012 21:23:45 -0300 Subject: [PATCH] [media] stk1160: Fix s_fmt and try_fmt implementation The driver was expecting to get a valid pixelformat on s_fmt and try_fmt. This is wrong, since the user may pass a bitmask and expect the driver to change it, returning a valid (fourcc) pixelformat. This problem was spotted by v4l2-compliance.
