There was some checkpatch noises in some of the patches - please verify
with "--strict".
Mostly alignment of parameters with open parantesis
Sample - but there was similar issues in other patches:

8788b59decc8 (HEAD -> drm-misc-next) drm: kirin: Move ade drm init to kirin drm drv
-:208: CHECK:PARENTHESIS_ALIGNMENT: Alignment should match open parenthesis
#208: FILE: drivers/gpu/drm/hisilicon/kirin/kirin_drm_drv.c:41:
+static int kirin_drm_crtc_init(struct drm_device *dev, struct drm_crtc *crtc,
+				struct drm_plane *plane,

-:244: CHECK:PARENTHESIS_ALIGNMENT: Alignment should match open parenthesis
#244: FILE: drivers/gpu/drm/hisilicon/kirin/kirin_drm_drv.c:77:
+	ret = drm_universal_plane_init(dev, plane, 1, data->plane_funcs,
+				data->channel_formats,

-:271: CHECK:PARENTHESIS_ALIGNMENT: Alignment should match open parenthesis
#271: FILE: drivers/gpu/drm/hisilicon/kirin/kirin_drm_drv.c:104:
+static int kirin_drm_private_init(struct drm_device *dev,
+				const struct kirin_drm_data *driver_data)




And then the build failed like this:
 LD [M]  drivers/gpu/drm/hisilicon/kirin/kirin-drm.o

It was a simple allmodconfig build where I did:

make drivers/gpu/drm/hisilicon/

Please fix and resend. I did not look further.
