From 3c1c2fce64fdfa2f0c0ff4fffb3bb171ea6361ca Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Tue, 5 Jul 2011 13:45:19 +0200 Subject: HID: wiimote: Add sysfs support to wiimote driver Add sysfs files for each led of the wiimote. Writing 1 to the file enables the led and 0 disables the led. We do not need memory barriers when checking wdata->ready since we use a spinlock directly after it.
