Subject: [PATCH 2/6] mfd: cros_ec: free IRQ automatically
Date: Mon, 19 Feb 2018 23:40:43 +0100 [thread overview]
Message-ID: <20180219224043.21383-1-enric.balletbo@collabora.com> (raw)
From: Vincent Palatin <vpalatin@chromium.org>
Free the IRQ we might have requested when removing the cros_ec device,
so we can unload and reload the driver properly.
