Hello Alex Deucher,

This is a semi-automatic email about new static checker warnings.

The patch b530602fd462: "drm/radeon: add audio support for DCE6/8 GPUs (v12)" from Jul 31, 2013, leads to the following Smatch complaint:

drivers/gpu/drm/radeon/dce6_afmt.c:91 dce6_afmt_select_pin() warn: variable dereferenced before check 'dig->afmt->pin' (see line 89)

drivers/gpu/drm/radeon/dce6_afmt.c 88 u32 offset = dig->afmt->offset; 89 u32 id = dig->afmt->pin->id; ^^^^^^^^^^^^^^^^^^ Patch adds dereference.

90 91 if (!dig->afmt->pin) ^^^^^^^^^^^^^^^ Patch adds check.

92 return; 93

regards, dan carpenter
