media: dvbdev: Initialize sbuf
[ Upstream commit 17d1316de0d7dc1bdc5d6e3ad4efd30a9bf1a381 ]
Because the size passed to copy_from_user() cannot be known beforehand,
it needs to be checked during runtime with check_object_size. That makes
gcc believe that the content of sbuf can be used before init.
Fix:
./include/linux/thread_info.h:215:17: warning: ‘sbuf’ may be used uninitialized [-Wmaybe-uninitialized]
