From 3700df921401b336bc03043c7d49c32bc2419b13 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 4 Nov 2017 22:02:46 +0100 Subject: [PATCH] usb: gadget: bcm63xx_udc: Use common error handling code in bcm63xx_udc_probe() 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.
