Subject: [PATCH] Staging: fbtft: Fix wrong check in fbtft_write_wmem16_bus8()
Date: Mon, 15 Jul 2019 16:30:02 +0200
Message-ID: <20190715143003.12819-1-nsaenzjulienne@suse.de> (raw)

We actually want to set the gpio pin if it's avilable, not the other way
around.

Fixes: c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor interface")
