From: Imre Deak Date: Mon, 14 Aug 2017 15:15:29 +0000 (+0300) Subject: drm/i915: Work around GCC anonymous union initialization bug X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0a445945be6d10c5e6fd5599a27e43b6a7fdf14d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Work around GCC anonymous union initialization bug GCC 4.4 can't cope with anonymous union initializers which seems to be a bug in that version (see the Reference) and is fixed since GCC version 4.6. A workaround which is also used elsewhere in the kernel for the same purpose is to wrap the initialization in curly braces, so do the same here.
