From b8a832b1c0a70531b4bd69a67aa0bf72f6f2dc34 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Mon, 15 Dec 2008 13:12:08 +0100 Subject: [PATCH] HID: fix reference count leak hidraw The hidraw subsystem has a bug that prevents the close syscall from ever reaching the low level driver, leading to a resource leak. Fix by replacing postdecrement with predecrement.
