[PATCH 01/30] media: dvbdev: handle ENOMEM error at dvb_module_probe()

[Mauro Carvalho Chehab]

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)
