Subject: [PATCH v2 2/2] misc: mei: client.c: fix problem of return '-EOVERFLOW' in mei_cl_write
Date:   Mon, 20 Nov 2023 17:55:26 +0800

Clang static analyzer complains that value stored to 'rets' is never
read.Let 'buf_len = -EOVERFLOW' to make sure we can return '-EOVERFLOW'.

Fixes: 8c8d964ce90f ("mei: move hbuf_depth from the mei device to the hw modules")
