From 0e781c2258ffb2a42bf44f62dea8662f38cbfd34 Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Fri, 15 Jan 2016 18:41:34 +0100 Subject: usb-misc: sisusbvga: fix error path Remove a call to dev_err() that was reporting an unsuccesful call to kmalloc(), as reporting memory allocation failures is redundant. Instead of logging the error, clean up previously allocated resources and abort the probe with -ENOMEM. Before this change sisusb->SiS_Pr could be dereferenced even if null after failure of memory allocation.
