Subject: [PATCH] gpio: htc-egpio: Remove unused exported htc_egpio_get_wakeup_irq()
Date: Tue, 10 Sep 2019 16:15:29 +0200 [thread overview]
Message-ID: <20190910141529.21030-1-geert+renesas@glider.be> (raw)
This function was never used upstream, and is a relic of the original
handhelds.org code the htc-egpio driver was based on.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
