Subject: [PATCH 4.14 093/167] drm/amd/powerplay: Fix smu_table_entry.handle type

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andrey Grodzovsky <andrey.grodzovsky@....com>

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.
