Subject: [PATCH] ch7006: correctly handling failed allocation
Date: Thu, 28 Jan 2016 18:54:36 -0500	[thread overview]
Message-ID: <1454025276-13465-1-git-send-email-wuninsu@gmail.com> (raw)

Since drm_property_create_range can be failed in memory pressure,
it needs to be checked and return -ENOMEM.
