From c60fa555b11b25386b355c141d90cbee361c3eec Mon Sep 17 00:00:00 2001 From: Pan Bian Date: Mon, 5 Dec 2016 19:37:24 +0800 Subject: [PATCH] HID: usbhid: fix improper return value Function hid_post_reset() should return negative error codes on failures. However, in its implementation, it incorrectly returns 1. This patch fixes the bug, returning proper error codes on failures.
