We may have fused or unused pipes in our system. Let's check that the pipe in question is within limits of accessible pipes. In case, that we are not able to access the pipe, we return early with a warning. v2: Rephrasing of the commit message (Jani) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103206 Reported-by: Thomas Gleixner Tested-by: Jaswinder Singh Rajput Suggested-by: Jani Nikula Reviewed-by: Jani Nikula Signed-off-by: Mika Kahola Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/1513584243-12607-1-git-send-email-mika.kahola@intel.com (cherry picked from commit 0b7029b7e43fda1304c181a3ade0b429b9edcd9d) Signed-off-by: Rodrigo Vivi Cc: # v4.10+ Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/i915/intel_audio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/gpu/drm/i915/intel_audio.c +++ b/drivers/gpu/drm/i915/intel_audio.c @@ -754,7 +754,7 @@ static struct intel_encoder *get_saved_e { struct intel_encoder *encoder; - if (WARN_ON(pipe >= INTEL_INFO(dev_priv)->num_pipes)) + if (WARN_ON(pipe >= ARRAY_SIZE(dev_priv->av_enc_map))) return NULL; /* MST */ Patches currently in stable-queue which might be from mika.kahola@intel.com are queue-4.15/drm-i915-audio-fix-check-for-av_enc_map-overflow.patch queue-4.15/drm-i915-check-for-fused-or-unused-pipes.patch
