Subject: [PATCH] Bluetooth: Improve support for Actions Semi ATS2851 based

 devices

References: bsc#1012628

Patch-mainline: 6.3.4

Git-commit: 7c2b2d2d0cb658aa543e11e90ae95621d3cb5fe6

[ 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)
