From b684e9bc750b6349ff59f1b1ab4397cae255765f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 25 Jun 2016 08:20:30 +0100 Subject: [PATCH] x86/efi: Remove the unused efi_get_time() function Nothing calls the efi_get_time() function on x86, but it does suffer from the 32-bit time_t overflow in 2038. This removes the function, we can always put it back in case we need it later.
