The entry_setup_frames is defined as u8 type, else(entry_setup_frames < 0) is invalid. At the same time, the return value of function intel_psr_entry_setup_frames is also of type int. so modified its type to int. ./drivers/gpu/drm/i915/display/intel_psr.c:1336:5-23: WARNING: Unsigned expression compared with zero: entry_setup_frames >= 0.
