From ae2938c358430beab098fbfac843532c25b36372 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Sat, 23 Jan 2021 14:25:00 +0000 Subject: usb: musb: Fix NULL check on struct musb_request field The 'request' variable is a pointer to the 'request' field of the struct musb_request 'req' pointer. It only worked until now because the 'request' field is the first one in the musb_request structure, but as soon as that changes, the check will be invalid. Fix it preventively by doing the NULL-check on the 'req' pointer instead.
