From ebecc6c48f39b3c549bee1e4ecb9be01bf341a0f Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Mon, 19 Aug 2019 23:38:02 +0800 Subject: [PATCH] drm/amd/powerplay: fix variable type errors in smu_v11_0_setup_pptable fix size type errors, from uint32_t to uint16_t. it will cause only initializes the highest 16 bits in smu_get_atom_data_table function. bug report: This fixes the following static checker warning. drivers/gpu/drm/amd/amdgpu/../powerplay/smu_v11_0.c:390 smu_v11_0_setup_pptable() warn: passing casted pointer '&size' to 'smu_get_atom_data_table()' 32 vs 16.
