From 8f310fb91657b2000521b1ad67169e38ebded37a Mon Sep 17 00:00:00 2001 From: Harshit Mogalapalli Date: Wed, 5 Apr 2023 23:31:18 -0700 Subject: [PATCH] niu: Fix missing unwind goto in niu_alloc_channels() [ Upstream commit 8ce07be703456acb00e83d99f3b8036252c33b02 ] Smatch reports: drivers/net/ethernet/sun/niu.c:4525 niu_alloc_channels() warn: missing unwind goto? If niu_rbr_fill() fails, then we are directly returning 'err' without freeing the channels. Fix this by changing direct return to a goto 'out_err'.
