Date: Mon, 4 Jan 2010 10:50:23 -0800 From: Dmitry Torokhov <dmitry.torokhov@...il.com> To: Greg KH <gregkh@...e.de> Cc: LKML <linux-kernel@...r.kernel.org> Subject: Need to take dev->sem, do it directly or use wrapper? Greg, I was looking at restructuring serio a bit and rely more on the infrastructure in the drivre core now that it is more flexible. It all looks good except for one detail - serio provides "reconnect" method which allows user to reinitialize a port whithout tearing down its children input devices. To properly serialize with probe(), remove() and other bus operations I'd need to take dev->sem semaphore. I(s bus code allowed to do this? Can I do it directly or we need to add a wrapper (like device_serialize_access(dev, bool))?
