From c5537ea531d83b7d02ce2d52a5e2b90f526449d0 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 20 Oct 2011 18:43:07 +0200 Subject: [PATCH] usb: dwc3: debugfs: hold the lock in during mode change The read and write operation is atomic and we need no locking around this operations. What we need however is a lock that is held which ensures that the content of the DWC3_GCTL has not been changed. With this, the conten may have been change changed after the first but before our write back. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi --- Reading git-format-patch failed
