Subject: [PATCH] [media] msi2500: Delete an unnecessary check in msi2500_set_usb_adc()
Date: Tue, 29 Dec 2015 12:37:16 +0100	[thread overview]
Message-ID: <5682706C.5010504@users.sourceforge.net> (raw)
In-Reply-To: <566ABCD9.1060404@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 29 Dec 2015 12:32:41 +0100

This issue was detected by using the Coccinelle software.

Return the value from a call of the msi2500_ctrl_msg() function
without using an extra check for the variable "ret" at the end.
