Add functions to handle multiplanar format ioctls, calling the generic format ioctls functions when possible. Signed-off-by: André Almeida <andrealmeid@collabora.com> --- Change in v4: - Split from multiplanar parameter commit - Use `IS_MULTIPLANAR` instead of `multiplanar` - Move "Functions to handle..." to commit 5 Change in v3: - Remove functions that only did the `IS_MULTIPLANAR(vcap)` check - Squash with multiplanar parameter commit Change in v2: - Fix alignment drivers/media/platform/vimc/vimc-capture.c | 63 +++++++++++++++++++--- 1 file changed, 57 insertions(+), 6 deletions(-)
