From 6ea91bf8055b18b24828c449e33572ca9a9832eb Mon Sep 17 00:00:00 2001 From: Andrew Goodbody Date: Tue, 30 Sep 2025 16:52:22 +0100 Subject: [PATCH] usb: musb-new: Null check before dereference A null check for the variable 'data' was introduced before dereferencing it for set_phy_power but other uses were not so protected. Add the null check for other dereferences of 'data'. This issue was found by Smatch.
