X-Git-Tag: v4.14.21~75
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dc2b0e41fc5e6d11fe4539317e57cf84c67cd18d;p=platform%2Fkernel%2Flinux-exynos.git

drm/amd/powerplay: Fix smu_table_entry.handle type

commit adab595d16abe48e9c097f000bf8921d35b28fb7 upstream.

The handle describes kernel logical address, should be
unsigned long and not uint32_t.
Fixes KASAN error and GFP on driver unload.
