Subject: [PATCH 1/2] drm/etnaviv: fix etnaviv_cmdbuf_suballoc_new return value
Date: Fri, 5 Jul 2019 19:15:35 +0200 [thread overview]
Message-ID: <20190705171536.26727-1-l.stach@pengutronix.de> (raw)
The call site expects to get either a valid suballoc or an error
pointer, so a NULL return will not be treated as an error. Make
sure to always return a proper error pointer in case something goes
wrong.
