Subject: drm/amdgpu: initialize amdgpu_cgs_acpi_eval_object result value

From: Nicolas Iooss <[email protected]>

commit 29b9c528b8c295911e8b1e515273e89a2b7fa2d8 upstream.

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++) {
                        ^~~~~~~~~

            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
