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. Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
