Subject: [PATCH] spufs fix spu_acquire_runnable error path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0106246594a05f02a6be6ee4695c7584c758fa7f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[PATCH] spufs fix spu_acquire_runnable error path

When spu_activate fails in spu_acquire_runnable, the
state must still be SPU_STATE_SAVED, we were
incorrectly setting it to SPU_STATE_RUNNABLE.
