Subject: [PATCH 6/6] xhci: remove unused lpm_failed_dev member from struct xhci_hcd
Date: Wed, 21 Sep 2022 15:34:50 +0300 [thread overview]
Message-ID: <20220921123450.671459-7-mathias.nyman@linux.intel.com> (raw)
In-Reply-To: <20220921123450.671459-1-mathias.nyman@linux.intel.com>
xhci used to test if link power management (LPM) capable USB2 devices
really could enter and exit L1 state link state.
Failed devices were added to a lpm_failed_dev list.
This feature was removed 9 years ago in
commit de68bab4fa96 ("usb: Don't enable USB 2.0 Link PM by default.")
but lpm_failed_dev member was still left.
Remove it now.
