Bluetooth: btrtl: Fix an issue that failing to download the FW which size is over 32K bytes

2019-09-05T15:27:32+00:00

Fix the issue that when the FW size is 32K+, it will fail for the download
process because of the incorrect index.

When firmware patch length is over 32K, "dl_cmd->index" may >= 0x80. It
will be thought as "data end" that download process will not complete.
However, driver should recount the index from 1.

These printing macros already add a trailing newline, so drop these
unnecessary additional newlines.

Bluetooth: btrtl: Remove redundant prefix from calls to rtl_dev macros

2019-09-05T15:27:22+00:00

the rtl: or RTL: prefix in the string is pointless. The rtl_dev_* macros
already does that.

2019-07-06T11:00:58+00:00

This device is functionally equivalent to the BT part of the RTL8723DE,
uses the same firmware, but the LMP subversion and HCI revision are unique.

Bluetooth: btrtl: HCI reset on close for Realtek BT chip

2019-07-06T10:32:50+00:00

Realtek RTL8822BE BT chip on ASUS X420FA cannot be turned on correctly
after on-off several times. Bluetooth daemon sets BT mode failed when
this issue happens. Scanning must be active while turning off for this
bug to be hit.

bluetoothd[1576]: Failed to set mode: Failed (0x03)

If BT is turned off, then turned on again, it works correctly again.

According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set
during probing. So, this patch makes Realtek's BT reset on close to fix
this issue.

Bluetooth: btrtl: Restore old logic to assume firmware is already loaded

2019-01-28T12:23:59+00:00

Realtek bluetooth may not work after reboot:
[   12.446130] Bluetooth: hci0: RTL: rtl: unknown IC info, lmp subver a99e, hci rev 826c, hci ver 0008

This is a regression introduced by commit 26503ad25de8 ("Bluetooth:
btrtl: split the device initialization into smaller parts"). The new
logic errors out early when no matching IC info can be found, in this
case it means the firmware is already loaded.

So let's assume the firmware is already loaded when we can't find
matching IC info, like the old logic did.
