Subject: [PATCH 09/18] HID: Return an error code only as a constant in hid_allocate_device()
Date: Tue, 7 Feb 2017 20:51:37 +0100	[thread overview]
Message-ID: <58187414-2ced-17cb-cb6a-0fe87d0e5fac@users.sourceforge.net> (raw)
In-Reply-To: <edd25fcd-8625-2469-fa28-2315f81b6b8e@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 7 Feb 2017 19:17:36 +0100

* Return an error code without storing it in an intermediate variable.

* Delete the local variable "ret" which became unnecessary with
  this refactoring.
