Subject: Bluetooth: Skip unconfigured init procedure for raw-only devices
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cc78b44ba2231d6a92707407cd199b2e05fe3528;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Bluetooth: Skip unconfigured init procedure for raw-only devices

When the driver sets HCI_QUIRK_RAW_DEVICE, the controller will be set
as unconfigured. However running the unconfigured init procecure is
not useful since raw-only devices are not allowed to change its
configuration. This change skips the init procedure and just allows
user channel operation for this device.
