Subject: [PATCH 1/2] input: keyboard: imx: no need to control interrupt status in event check
Date: Fri, 29 Mar 2019 07:00:43 +0000	[thread overview]
Message-ID: <1553842562-8481-1-git-send-email-Anson.Huang@nxp.com> (raw)

There is no need to enable release interrupt and disable depress
interrupt in event check, as a timer is setup for checking these
events rather than interrupts.
