Subject: [RESEND PATCH] mfd: stmpe: honor gpio interrupt probe deferral
Date: Tue, 14 Aug 2018 15:01:54 +0200 [thread overview]
Message-ID: <20180814130155.29973-1-marcel@ziswiler.com> (raw)
From: Marcel Ziswiler <marcel.ziswiler@toradex.com>
Actually honor probe deferral in trying to get the GPIO interrupt as
of_get_named_gpio_flags() in stmpe_of_probe() may as well just do so.
