From: Keith Packard Date: Wed, 9 Nov 2011 17:57:50 +0000 (-0800) Subject: drm/i915: Module parameters using '-1' as default must be signed type X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4415e63b13c68c2f56d16d400a1ae345f68cf655;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Module parameters using '-1' as default must be signed type Testing i915_panel_use_ssc for the default value was broken, so the driver would never autodetect the correct value.
