From 288ef567ab7b43f19838afbe12b471f1ff5fdfa3 Mon Sep 17 00:00:00 2001 From: Huacai Chen <chenhc@lemote.com> Date: Mon, 11 May 2015 11:08:22 +0800 Subject: [PATCH] staging: sm750: Fix lynxfb_ops_imageblit() if image->depth != 1 If image->depth != 1, lynxfb_ops_imageblit() should fallback to call cfb_imageblit(), not return directly. Otherwise it can't display the boot logo.
