[PATCH] drm/i915/gvt: remove redundant -Wall

From: Nick Desaulniers
Date: Sun May 21 2017 - 03:16:12 EST


This flag is already set in the top level Makefile of the kernel.

Also, by having set CONFIG_DRM_I915_GVT, thereby appending -Wall to
ccflags, you undo all the -Wno-* cflags previously set in the Make
variable KBUILD_CFLAGS.

For example:

cc foo.c -Wall -Wno-format -Wall

resets -Wformat.

I verified that -Wall was redundant by compiling with V=1:
make V=1 -j4 drivers/gpu/drm/i915/i915_gem_request.o
