From e41e6feb3d3b33f0793df6a1d9da20c8096a346e Mon Sep 17 00:00:00 2001 From: Andrew Goodbody Date: Mon, 29 Sep 2025 17:53:11 +0100 Subject: [PATCH] usb: ehci: exynos: variable node should be signed THe variable node is assigned to the return value of a function that returns an int. It is tested for being negative and then passed as an argument to a function that takes an int. So 'node' should not be declared as unsigned. Correct it. This issue was found by Smatch.
