Any chance to get my HDA beep updates merged to linux-next tree?

[ALSA] hda_intel: Digital PC Beep - change behaviour for input layer
[ALSA] hda_intel: Digital PC Beep - delay input device unregistration
[ALSA] hda: beep - add missing cancel_delayed_work

Reasons for merge:

- it's tested
- it's compatible with all kernels (including ones without
   the future input layer modifications)
- the code is more structured which can help us to rebind
   "on request" input registration to another logic later
- Beep mute switch now disables the tone generator on the off request -
   it might be considered as bug in the previous beep code
