Series [resend,1/3] gpiolib: acpi: Correct comment for HP x2 10 honor_wakeup quirk | expand

Commit Message

Hans de Goede Feb. 25, 2020, 10:27 a.m. UTC 
There are at least 3 variants of the HP x2 10 models:

Bay Trail SoC + AXP288 PMIC
Cherry Trail SoC + AXP288 PMIC
Cherry Trail SoC + TI PMIC

Like on the Bay Trail + AXP288 PMIC model, we also need to ignore wakeups
for the GPIO which is (ab)used for embedded-controller events on the
Cherry Trail + AXP288 PMIC model.
