From c4c285da1ee18582ace366f07e56e355c20ebc49 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 29 Jun 2017 14:21:32 +0200 Subject: [PATCH] Bluetooth: hci_bcm: Add active_low irq polarity quirk for Asus T100CHI Just like the T100TA the host-wake irq on the Asus T100CHI is active low. Having a quirk for this is actually extra important on the T100CHI as it ships with a bluetooth keyboard dock, which does not work properly without this quirk.
