Subject: [PATCH] ipmi: ssif_bmc: Uninitialized return in ssif_bmc_write()
Date: Fri, 30 Jul 2021 18:08:01 +0300	[thread overview]
Message-ID: <20210730150801.GA1074@kili> (raw)

I accidentally introduced a bug in my previous patch.  The "ret"
variable needs to be initialized to prevent returning uninitialized
data.

Fixes: f9714eb04364 ("ipmi: ssif_bmc: Return -EFAULT if copy_from_user() fails")
