Subject: [PATCH 1/3] net: usb: cdc_ncm: emit dev_err on error paths
Date: Fri, 15 Jan 2021 21:26:21 -0800 [thread overview]
Message-ID: <20210116052623.3196274-1-grundler@chromium.org> (raw)
Several error paths in bind/probe code will only emit
output using dev_dbg. But if we are going to fail the
bind/probe, emit related output with "err" priority.
