Subject: [PATCH] input: synaptics-rmi4: remove redundant null check on rmi_dev
Date: Wed, 21 Dec 2016 14:41:04 +0000	[thread overview]
Message-ID: <> (raw)

From: Colin Ian King <>

rmi_dev is currently being dereferenced before it null checked,
however, after deeper inspecting, rmi_dev can never be null,
so just remove this redundant check. Thanks to Dmitry Torokhov for
noticing that we can remove the null check.

Fixes CoverityScan CID 1391218 ("Dereference before null check")
