Subject: Bluetooth: remove struct hci_chan_hash
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2c33c06a8fd2f784ca763ad150d5d63c3c49946e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: remove struct hci_chan_hash

Only the list member of the struct was used, so we now fold it into
hci_conn.
