Subject: [patch] HID: uclogic: fix limit in uclogic_tablet_enable()
Date: Wed, 29 Jul 2015 10:16:06 +0000 [thread overview]
Message-ID: <20150729101606.GA12100@mwanda> (raw)
The limit should be ARRAY_SIZE(params) (5 elements) here instead of
sizeof(params) (20 bytes).
Fixes: 08177f40bd00 ('HID: uclogic: merge hid-huion driver in hid-uclogic')
