Subject: Bluetooth: mgmt: Check for HCI_UP in update_eir() and update_class()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7770c4aacaf34fb69cb2acfb7469e9b4e34f1674;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: mgmt: Check for HCI_UP in update_eir() and update_class()

These functions should just silently fail when we're not powered on
instead of trying to send HCI commands.
