From baec2700bad81e1b08c81240c382b46613ccb981 Mon Sep 17 00:00:00 2001 From: Kou Ishizaki Date: Thu, 9 Oct 2008 10:45:49 +1100 Subject: powerpc/spufs: add a missing mutex_unlock commit 6747c2ee8abf749e63fee8cd01a9ee293e6a4247 upstream. 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.
