From c0e625c41abbcc12c4981823889e3dc126252fb5 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Mon, 23 Jan 2017 14:20:21 +0200 Subject: [PATCH] usb: host: xhci: convert several if() to a single switch statement when getting endpoint type, a switch statement looks better than a series of if () branches. There are no functional changes with this patch, cleanup only.
