Subject: [PATCH AUTOSEL 6.2 47/53] Bluetooth: Improve support for Actions Semi ATS2851 based devices

From: Raul Cheleguini <[email protected]>

[ Upstream commit 7c2b2d2d0cb658aa543e11e90ae95621d3cb5fe6 ]

Add two more quirks to resume the device initialization and basic
operation as the device seems not to support "Read Transmit Power"
and "Set Extended Scan Parameters".

< HCI Command: LE Read Transmit Power (0x08|0x004b) plen 0
> HCI Event: Command Status (0x0f) plen 4
LE Read Transmit Power (0x08|0x004b) ncmd 1
Status: Unknown HCI Command (0x01)

< HCI Command: LE Set Extended Scan Parameters (0x08|0x0041) plen 8
Own address type: Random (0x01)
Filter policy: Accept all advertisement (0x00)
PHYs: 0x01
Entry 0: LE 1M
Type: Active (0x01)
Interval: 11.250 msec (0x0012)
Window: 11.250 msec (0x0012)
> HCI Event: Command Status (0x0f) plen 4
LE Set Extended Scan Parameters (0x08|0x0041) ncmd 1
Status: Unknown HCI Command (0x01)
