[PATCH AUTOSEL 6.13 44/49] 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 6.13 47/49] Bluetooth: qca: simplify WCN399x NVM loading

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.
