Subject[PATCH 4.9 040/199] usb: dwc3: dont log probe deferrals; but do log other error codes
Date
From: Brian Norris <briannorris@chromium.org>

[ Upstream commit 408d3ba006af57380fa48858b39f72fde6405031 ]

It's not very useful to repeat a bunch of probe deferral errors. And
it's also not very useful to log "failed" without telling the error
code.
