From: Dave Stevenson <[email protected]>
Before commit "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping"
there was a need to ensure that there were sufficient buffers supplied from
the user to cover those being sent to the VPU (always 1).
Now the buffers are linked 1:1 between MMAL and V4L2,
therefore there is no need for that check, and indeed it is wrong
as there is no need to submit all the buffers before starting streaming.
Fixes: 938416707071 ("staging: bcm2835-camera: Remove V4L2/MMAL buffer
remapping")
