drm-tip dmesg with drm.debug=0x1e from Lenovo Miix 320-10ICR
Hello!
I find that brightness adjustment is broken on Lenovo Miix 320-10ICR since
Linux 5.3rc1, git bisect lead to this commit:
<a href="https://github.com/torvalds/linux/commit/4a6ef8e37c4d9a40f09438068da1734fd965bd75">https://github.com/torvalds/linux/commit/4a6ef8e37c4d9a40f09438068da1734fd965bd75</a>
drm-tip 2019-07-30 4040b4c4ab647422d82100c8b091d34b6a82f572 log with
drm.debug=0x1e log_buf_len=8M where I trying to adjust brightness is attached.
Brightness adjustment works fine on Linux 5.0-5.2 (earlies releases wasn't
tested).</pre>
