Subject: [patch] [media] m5mols: potential uninitialized variable
Date: Tue, 15 Mar 2016 10:07:10 +0300	[thread overview]
Message-ID: <20160315070710.GD13560@mwanda> (raw)

Smatch complains that there are some paths where "status" isn't
initialized.  The code does assume that m5mols_read_u8() can fail so it
seems as if Smatch is correct.

Let's initialize it to REG_ISO_AUTO which is zero.
