From 38f13bf801303a38316a12e06dbfc6fdc410f8ed Mon Sep 17 00:00:00 2001 From: Choong Yong Liang Date: Mon, 10 Mar 2025 13:08:35 +0800 Subject: [PATCH] stmmac: intel: Fix warning message for return value in intel_tsn_lane_is_available() Fix the warning "warn: missing error code? 'ret'" in the intel_tsn_lane_is_available() function. The function now returns 0 to indicate that a TSN lane was found and returns -EINVAL when it is not found.
