[PATCH v2 0/3] Huawei laptops WMI & sound fixes

[Ayman Bagabas]

This patch set fixes some of the issues with Huawei laptops. 

[PATCH v2 1/3] 
The first patch adds support for missing hotkeys on some models. Some hotkeys,
like brightness keys, work out of the box on these models.

[PATCH v2 2/3]
This one enables the front speakers on the Huawei Matebook X Pro (MBXP). This
solves bug 200501 https://bugzilla.kernel.org/show_bug.cgi?id=200501
It simply uses the pins configurations generated by hdajackretast using the
settings posted on the bug page https://imgur.com/a/N1xsCVZ

[PATCH v2 3/3]
This enables the micmute LED on Huawei laptops. It calls an WMI method, using
PATCH #1, to turn the micmute LED on/off.
