[PATCH] Bluetooth: btusb: Edit the logical value for Realtek Bluetooth reset
From: max.chou
Date: Tue Nov 26 2019 - 22:01:47 EST
From: Max Chou <max.chou@xxxxxxxxxxx>
It should be pull low and pull high on the physical line for the Realtek
Bluetooth reset. gpiod_set_value_cansleep() takes ACTIVE_LOW status for
the logical value settings, so the original commit should be corrected.
