From f8b5d353394f39d694a58681069307132b273e3c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Noralf=20Tr=C3=B8nnes?= Date: Tue, 17 Sep 2019 19:18:41 +0200 Subject: [PATCH] staging/fbtft: Depend on OF MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit BugLink: https://bugs.launchpad.net/bugs/1848750 commit 63f2b1677fba11c5bd02089f25c13421948905f5 upstream. Commit c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor interface") removed setting gpios via platform data. This means that fbtft will now only work with Device Tree so set the dependency. This also prevents a NULL pointer deref on non-DT platform because fbtftops.request_gpios is not set in that case anymore.
