From: Johan Hedberg Date: Wed, 22 Feb 2012 18:14:22 +0000 (+0200) Subject: Bluetooth: Fix read_name updating when HCI_SETUP is not set X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db99b5fc77e6cec47d80703b471f1efe04527d2f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git Bluetooth: Fix read_name updating when HCI_SETUP is not set The local name should only be updated as a consequence of a hci_read_local_name if we are in the HCI_SETUP state. In all other scenarios it should only be updated through hci_write_local_name.
