From 771ea160e68f69723c074a13110459327896d35e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Noralf=20Tr=C3=B8nnes?= Date: Mon, 22 Jul 2019 12:43:04 +0200 Subject: [PATCH] drm/tinydrm/mipi-dbi: Move cmdlock mutex init MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit cmdlock protects command execution so put it in mipi_dbi_spi_init() where it conceptually belongs. This is prep work for the splitting of struct mipi_dbi.
