From 3138887bd8d18173f3c2baf1e43621c49090cd27 Mon Sep 17 00:00:00 2001 From: tpugliese Date: Mon, 20 May 2013 15:09:05 -0500 Subject: [PATCH] usb: uwb: use correct locking calls for rc data The rc object's members can be accessed from both a timer and URB callback. Use spin_*_irq instead of spin_*_bh.
