powerpc/spufs: add a missing mutex_unlock
A mutex_unlock(&gang->aff_mutex) in spufs_create_context() is missing in case spufs_context_open() fails. As a result, spu_create syscall and spu_get_idle() may block. This patch adds the mutex_unlock. Signed-off-by: Kou Ishizaki <kou.ishizaki@toshiba.co.jp> Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Acked-by: Andre Detsch <adetsch@br.ibm.com>
