From f78fff4648bb0a797359dac69792463efd22bb00 Mon Sep 17 00:00:00 2001 From: Su Hui Date: Mon, 20 Nov 2023 17:55:26 +0800 Subject: [PATCH] misc: mei: client.c: fix problem of return '-EOVERFLOW' in mei_cl_write [ Upstream commit ee6236027218f8531916f1c5caa5dc330379f287 ] Clang static analyzer complains that value stored to 'rets' is never read.Let 'buf_len = -EOVERFLOW' to make sure we can return '-EOVERFLOW'.
