Subject: [PATCH 6/6] xhci: Add bus number to some debug messages
Date: Fri, 20 Aug 2021 15:35:03 +0300 [thread overview]
Message-ID: <20210820123503.2605901-7-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20210820123503.2605901-1-mathias.nyman@linux.intel.com>
As we register two usb buses for each xHC, and systems with several
hosts are more and more common it is getting hard to follow the
flow of debug messages without knowing which bus they belong to
