Hi Takashi,
Looks like no more comment from others, what is your opinion on the
patchset, is it ok to merge or need to do some change?
Thanks,
Hui.

the changes in the v4:
- change the sound-core to sound and change the sound_core_debugfs_root
to sound_debugfs_root in the 0001-xxx.patch
- change kzalloc/kfree to kvzalloc/kvfree in the debugfs fops for
0001-xxx.patch and 0003-xxx.patch
- And if needed, I could squash 4 patches into 1 patch before merging.
the changes in the v3 (for easy to review, divide change into 4 patches):
- address the comment about the snd_jack_report() and _snd_jack_report(),
the v2 design is hard to understand and is hard to review, in the v3,
separate the jack_report to snd_jack_report() and snd_jack_inject_report(),
hw jack events call snd_jack_report() as before, if a jack contains multi
jack_kctl and the jack_kctl's sw_inject is enabled, the status and the
related input-dev's events will not be reproted. The injection events call
snd_jack_inject_report(). This change is squashed to 0001-xxx.patch, the
rest part of 0001-xxx.patch is same as v2.
- address the comment about folders'name in the 0002-xxx.patch, so far, drop
the '/', ',', '=' and ' ' from the folders' name.
- address the comment about adding more debugfs nodes in the 0003-xxx.patch,
it adds kctl_id, mask_bits, status and type.
- address the comment about save-n-restore jack's hw status in the
0004-xxx.patch, adding a hw_status_cache and save the last reported jack
hw event, once the sw_inject is disabled, will restore all jack_kctl's
state under the same snd_jack with hw_status_cache.
[snip]
the changes in the V2:
- using debugfs instead of sysfs
- using jack_ctrl to create a folder instead of snd_jack, since ASoC drivers
could create multi jack_ctrls within a snd_jack
- create a folder for each jack_ctrl instead for all jack_ctrls
