From ab104318f63997113b0ce7ac288e51359925ed79 Mon Sep 17 00:00:00 2001 From: Ruan Jinjie Date: Fri, 18 Aug 2023 13:05:04 +0800 Subject: [PATCH] net: lan966x: Fix return value check for vcap_get_rule() As Simon Horman suggests, update vcap_get_rule() to always return an ERR_PTR() and update the error detection conditions to use IS_ERR(), so use IS_ERR() to fix the return value issue.
