Subject: [PATCH] drm/i915: Ignore frequent clang warnings
Date: Tue, 7 Nov 2017 19:06:22 +0000 [thread overview]
Message-ID: <20171107190622.16681-1-chris@chris-wilson.co.uk> (raw)
In order to reduce the flood of common errors reported by clang, add
them to the exclusion list in the Makefile. The plan is to taken them
slowly, most of the -Wsign-compare fixes should be trivial, and may even
find a bug or two!
