Subject: [patch] thermal: cpu_cooling: check for allocation failure
Date: Mon, 30 Mar 2015 11:21:44 +0000 [thread overview]
Message-ID: <20150330112144.GC27144@mwanda> (raw)
If this fails, then we're likely in trouble anyway, but it's nice to
keep the code free from static checker warnings so you don't miss more
important bugs.
