[PATCH -next 3/3] arm: Delete similar code across of_flat_dt_match_machine and setup_machine_fdt

From: Xu Qiang
Date: Tue Jul 26 2022 - 23:13:23 EST


of_flat_dt_match_machine() print compatible content when its
return value is NULL, and setup_machine_fdt print again when
mdesc is NULL. So remove duplicate print codes in setup_machine_fdt.
