[PATCH 1/5] drm/amdgpu/pm: Use scnprintf() for avoiding potential buffer overflow

2020-03-11 Thread Takashi Iwai
Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf(). Also adjust the size argument passed to scnprintf() so that it really cuts off at the right remaining buffer length
