From df9ecb0cad14b952a2865f8b3af86b2bbadfab45 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 28 Oct 2015 00:50:37 -0200 Subject: [media] vb2: drop v4l2_format argument from queue_setup The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s).
