From: Paulo Zanoni Date: Tue, 7 Jul 2015 18:26:06 +0000 (-0300) Subject: drm/i915: add FBC_IN_DBG_MASTER no_fbc_reason X-Git-Tag: firefly_0821_release~176^2~721^2~33^2~278 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8935108528194918966757fa00ac986176fe9497;p=firefly-linux-kernel-4.4.55.git drm/i915: add FBC_IN_DBG_MASTER no_fbc_reason The poor in_dbg_master() check was the only one without a reason string. Give it a reason string so it won't feel excluded.
