[PATCH] amdgpu: replace snprintf in show functions with sysfs_emit

From: Qing Wang
Date: Fri Oct 15 2021 - 02:47:38 EST


show() must not use snprintf() when formatting the value to be
returned to user space.

Fix the following coccicheck warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_ucode.c:427:
WARNING: use scnprintf or sprintf.
