drm/amdgpu: initialize amdgpu_cgs_acpi_eval_object result value

2016-06-20T21:09:39Z

amdgpu_cgs_acpi_eval_object() returned the value of variable "result" without initializing it first. This bug has been found by compiling the kernel with clang. The compiler complained: drivers/gpu/drm/amd/amdgpu/amdgpu_cgs.c:972:14: error: variable 'result' is used uninitialized whenever 'for' loop exits because its condition is false [-Werror,-Wsometimes-uninitialized] for (i = 0; i < count; i++) { ^~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu_cgs.c:1011:9: note: uninitialized use occurs here return result; ^~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu_cgs.c:972:14: note: remove the condition if it is always true for (i = 0; i < count; i++) { ^~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu_cgs.c:864:12: note: initialize the variable 'result' to silence this warning int result; ^ = 0 Fixes: 3f1d35a03b3c ("drm/amdgpu: implement new cgs interface for acpi function") Signed-off-by: Nicolas Iooss Cc: stable@vger.kernel.org Signed-off-by: Alex Deucher
