From adefb69b1b94df29ea2df05cd838c0e032b2c473 Mon Sep 17 00:00:00 2001 From: Vinicius Costa Gomes Date: Sat, 14 Jul 2012 18:59:25 -0300 Subject: [PATCH] HID: uhid: Fix sending events with invalid data This was detected because events with invalid types were arriving to userspace. The code before this patch would only work for the first event in the queue (when uhid->tail is 0).
