Subject: Bluetooth: Fix EIR data clearing when powering off
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e59fda8dc14c173b74b5e9d5c8d72849d2ff6b5f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: Fix EIR data clearing when powering off

When powering off we should assume that the EIR data isn't valid
anymore. This patch makes sure it gets cleared in hci_dev_do_close and
thereby ensures that a correct new EIR is recreated when powering on
again.
