v2: - Added missing Suggested-by tag from Ritesh Harjani (IBM) drivers/char/nvram.c defines a static mutex 'nvram_mutex' which is never used. This results in a compiler warning on linux-next builds:
warning: 'nvram_mutex' defined but not used [-Wunused-variable] Remove the unused definition to avoid the warning.
