Hi Thomas,
I love your patch! Yet something to improve:
[auto build test ERROR on next-20200305]
[also build test ERROR on v5.6-rc4]
[cannot apply to rockchip/for-next shawnguo/for-next sunxi/sunxi/for-next tegra/for-next linus/master v5.6-rc4 v5.6-rc3 v5.6-rc2]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

The kirin driver uses an empty implementation for its encoder. Replace the code with the generic simple encoder. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> --- drivers/gpu/drm/hisilicon/kirin/dw_drm_dsi.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-)
