sound: oss: off by one bug
The problem is that in the original code sound_nblocks could go up to 1024 which would be an array overflow. This was found with a static checker and has been compile tested only. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
