media: v4l2-core: Rename second ioctl handlers argument to 'void *priv'

2025-08-13T06:33:59Z

The second argument to the ioctl handlers is not a file handle any more. Rename it from 'void *fh' to 'void *priv' in the V4L2 core, to avoid misconceptions. While at it, align function arguments in include/media/v4l2-mem2mem.h. Signed-off-by: Laurent Pinchart Signed-off-by: Hans Verkuil

media: v4l2-ctrls: Return the handler's error in v4l2_ctrl_handler_free()

2025-06-30T06:47:41Z

v4l2_ctrl_handler_free() used to return void but changing this to int, returning the handler's error code, enables the drivers to simply return the handler's error in this common error handling pattern: if (handler->error) return v4l2_ctrl_handler_free(handler); Suggested-by: Laurent Pinchart Signed-off-by: Sakari Ailus Reviewed-by: Laurent Pinchart Reviewed-by: Hans Verkuil Signed-off-by: Hans Verkuil

We use this logic in a couple of places. Refactor into a function. No functional change expected from this patch. Signed-off-by: Ricardo Ribalda Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: v4l2-ctrls: drop 'elems' argument from control type ops.

2022-09-24T06:49:06Z

The type ops for equal, init and validate have an elems argument, but this can be taken from struct v4l2_ctrl: ctrl->elems for equal and init, and ctrl->new_elems for validate (since you are validating a new control value). So drop this argument and update all callers. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
