media: dvbdev: handle ENOMEM error at dvb_module_probe()
If allocation of struct board_info fails, return NULL from dvb_module_probe(). Fix this warning: drivers/media/dvb-core/dvbdev.c:958 dvb_module_probe() error: potential null dereference 'board_info'. (kzalloc returns null) Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
