From 6d39944ee85fb46cd499b16231cbb10a00e3d878 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 8 Oct 2012 15:11:20 +0200 Subject: [PATCH] USB: EHCI: remove Netlogic XLS EHCI driver The platform code has been migrated to register the ehci-platform driver, thus obsoleting the ehci-xls driver, which can be removed.
