[PATCH AUTOSEL 6.12 42/47] Bluetooth: hci_uart: fix race during initialization

[Sasha Levin]

From: Arseniy Krasnov <avkrasnov@salutedevices.com>

[ Upstream commit 366ceff495f902182d42b6f41525c2474caf3f9a ]

'hci_register_dev()' calls power up function, which is executed by
kworker - 'hci_power_on()'. This function does access to bluetooth chip
using callbacks from 'hci_ldisc.c', for example 'hci_uart_send_frame()'.
Now 'hci_uart_send_frame()' checks 'HCI_UART_PROTO_READY' bit set, and
if not - it fails. Problem is that 'HCI_UART_PROTO_READY' is set after
'hci_register_dev()', and there is tiny chance that 'hci_power_on()' will
be executed before setting this bit. In that case HCI init logic fails.

Patch moves setting of 'HCI_UART_PROTO_READY' before calling function
'hci_uart_register_dev()'.

[PATCH AUTOSEL 6.12 44/47] Bluetooth: hci_qca: use the power sequencer for wcn6750

[Sasha Levin]

From: Janaki Ramaiah Thota <quic_janathot@quicinc.com>

[ Upstream commit 852cfdc7a5a5af54358325c1e0f490cc178d9664 ]

Older boards are having entry "enable-gpios" in dts, we can safely assume
latest boards which are supporting PMU node enrty will support power
sequencer.

[PATCH AUTOSEL 6.12 45/47] Bluetooth: qca: simplify WCN399x NVM loading

[Sasha Levin]

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

[ Upstream commit 1cc41b5092e3aa511454ec882c525af311bee631 ]

The WCN399x code has two separate cases for loading the NVM data. In
preparation to adding support for WCN3950, which also requires similar
quirk, split the "variant" to be specified explicitly and merge two
snprintfs into a single one.
