Subject: [PATCH] usb: gadget: bcm63xx_udc: Use common error handling code in
bcm63xx_udc_probe()
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 4 Nov 2017 22:02:46 +0100
Add a jump target so that a specific error message is stored only once
at the end of this function implementation.
Replace two calls of the function "dev_err" by goto statements.
This issue was detected by using the Coccinelle software.
