Subject: [PATCH 1/2] efi: add a function for transferring status to string
Date: Sat, 23 Mar 2019 16:37:23 +0800 [thread overview]
Message-ID: <20190323083724.1367-1-jlee@suse.com> (raw)
This function can be used to transfer EFI status code to string
for printing out debug message. Using this function can improve
the readability of log.
