Subject: amdgfx/gfx: don't use static objects for ce/de meta. (v2)
X-Git-Tag: v4.19~2077^2~56^2~43
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d81a2209498b6349a33f8741ca5a062dde84c043;p=platform%2Fkernel%2Flinux-rpi3.git

amdgfx/gfx: don't use static objects for ce/de meta. (v2)

This isn't safe if we have multiple GPUs plugged in, since
there is only one copy of this struct in the bss, just allocate
on stack, it's 40/108 bytes which should be safe.
