[ 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; ~~~~~~ ^~~~~~~~~~~~~~~~~~~~~
