Merge tag 'drm-misc-next-2021-07-22' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.15-rc1:

UAPI Changes:
- Remove sysfs stats for dma-buf attachments, as it causes a performance regression.
  Previous merge is not in a rc kernel yet, so no userspace regression possible.

Cross-subsystem Changes:
- Sanitize user input in kyro's viewport ioctl.
- Use refcount_t in fb_info->count
- Assorted fixes to dma-buf.
- Extend x86 efifb handling to all archs.
- Fix neofb divide by 0.
- Document corpro,gm7123 bridge dt bindings.

Core Changes:
- Slightly rework drm master handling.
- Cleanup vgaarb handling.
- Assorted fixes.

Driver Changes:
- Add support for ws2401 panel.
- Assorted fixes to stm, ast, bochs.
- Demidlayer ingenic irq.
