Hans Verkuil 1df7b8cd3a media: videobuf2: improve max_num_buffers sanity checks ... Ensure that drivers set max_num_buffers to a value >= 32. For now there is no reason for drivers to request a lower limit and doing so might potentially cause userspace issues. Note that the old check of > MAX_BUFFER_INDEX was pointless since q->max_num_buffers was already limited to MAX_BUFFER_INDEX or less. Also add a sanity check in __vb2_init_fileio(), returning -ENOSPC if a driver returns more than 32 buffers from VIDIOC_REQBUFS with count = q->min_reqbufs_allocation. The vb2_fileio_data struct only supports up to 32 buffers, so we need a check there. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>		2024-04-24 13:49:55 +02:00
