Subject: [PATCH] platform/x86: intel-hid: Support Lenovo ThinkPad X1 Tablet Gen 2
Git-commit: 56678a5f44ef5f0ad9a67194bbee2280c6286534
Patch-mainline: v5.12-rc5
References: git-fixes
Like a few other system the Lenovo ThinkPad X1 Tablet Gen 2 miss the
HEBC method, which prevent the power button from working. Add a quirk
to enable the button array on this system family and fix the power
button.
