Subject: [PATCH] powerpc/powernv/nvram: opal_nvram_write handle unknown OPAL errors
Date: Tue, 27 Mar 2018 01:02:33 +1000 [thread overview]
Message-ID: <20180326150233.23089-1-npiggin@gmail.com> (raw)
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.
