media: venus: remove invalid compat_ioctl32 handlervenus-for-v5.5-fixesvenus-for-next
v4l2_compat_ioctl32() is the function that calls into v4l2_file_operations->compat_ioctl32(), so setting that back to the same function leads to a trivial endless loop, followed by a kernel stack overrun. Remove the incorrect assignment. Cc: stable@vger.kernel.org Fixes: 7472c1c69138 ("[media] media: venus: vdec: add video decoder files") Fixes: aaaa93eda64b ("[media] media: venus: venc: add video encoder files") Signed-off-by: Arnd Bergmann <arnd@arndb.de>
