Hi Chris
I try to pick your patches, but found following issues:
drivers/gpu/drm/rockchip/dw-mipi-dsi.c: 在函数‘dw_mipi_dsi_register’中:
drivers/gpu/drm/rockchip/dw-mipi-dsi.c:1024:5: 错误： 提供给函数
‘drm_encoder_init’的实参太少
include/drm/drm_crtc.h:2220:5: 附注： 在此声明
make[4]: *** [drivers/gpu/drm/rockchip/dw-mipi-dsi.o] 错误 1
Can you rebase to newest Dave's drm-next and fix this problem?
Thanks.
