Subject: [PATCH] of_mdio: make of_mdiobus_register_{device|phy}() *void*
Date: Sun, 17 Apr 2016 01:05:19 +0300 [thread overview]
Message-ID: <1834436.v0N3sgcLOX@wasted.cogentembedded.com> (raw)
The results of of_mdiobus_register_{device|phy}() are never checked, so we
can make both these functions *void*...
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

The patch is against DaveM's 'net-next.git' repo.
