Subject: [PATCH 4.14 037/189] drm/msm/dsi: use correct enum in dsi_get_cmd_fmt
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Agner <stefan@...er.ch>
[ Upstream commit a4af89286f8fc382459308764ea05935dc477cdc ]
The function dsi_get_cmd_fmt returns enum dsi_cmd_dst_format,
use the correct enum value also for MIPI_DSI_FMT_RGB666/_PACKED.
This has been discovered using clang:
drivers/gpu/drm/msm/dsi/dsi_host.c:743:35: warning: implicit conversion
from enumeration type 'enum dsi_vid_dst_format' to different
enumeration type 'enum dsi_cmd_dst_format' [-Wenum-conversion]
case MIPI_DSI_FMT_RGB666: return VID_DST_FORMAT_RGB666;
