From 428733c72d03d7fca9e66bf7d44e9ac5eb4e12ea Mon Sep 17 00:00:00 2001 From: =?utf8?q?Guido=20G=C3=BCnther?= Date: Wed, 26 Jun 2019 12:37:49 +0200 Subject: [PATCH] drm/panel: jh057n00900: Don't use magic constant MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 0xBF isn't in any ST7703 data sheet so mark it as unknown. This avoids confusion on whether there is a missing command in that dsi_generic_write_seq() call.
