| H A D | opal-nvram.c | 741de617 Mon Mar 26 10:02:33 CDT 2018 Nicholas Piggin <npiggin@gmail.com> powerpc/powernv: Handle unknown OPAL errors in opal_nvram_write()
opal_nvram_write currently just assumes success if it encounters an
error other than OPAL_BUSY or OPAL_BUSY_EVENT. Have it return -EIO
on other errors instead.
Fixes: 628daa8d5abf ("powerpc/powernv: Add RTC and NVRAM support plus RTAS fallbacks")
