[PATCH 0/3] Bluetooth: hci_qca: fix post merge window regressions

[Bartosz Golaszewski]

Here are the fixes for regressions reported by Wren and Dmitry. I could
reproduce the crash on db820c and so I was able to test it but patch 2/3
could use a Tested-by from Wren on QCA6390.

[PATCH 1/3] Bluetooth: hci_qca: don't call pwrseq_power_off() twice for QCA6390

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Now that we call pwrseq_power_off() for all models that hold a valid
power sequencing handle, we can remove the switch case for QCA_6390. The
switch will now use the default label for this model but that's fine: if
it has the BT-enable GPIO than we should use it.

[PATCH 2/3] Bluetooth: hci_qca: fix QCA6390 support on non-DT platforms

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

QCA6390 can albo be used on non-DT systems so we must not make the power
sequencing the only option. Check if the serdev device consumes an OF
node. If so: honor the new contract as per the DT bindings. If not: fall
back to the previous behavior by falling through to the existing
default label.

Yes, I sent you an offlist message about it. You added:

The leading `+` caused patchwork to omit the tag. Just do:

[PATCH 3/3] Bluetooth: hci_qca: fix a NULL-pointer derefence at shutdown

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Unlike qca_regulator_init(), qca_power_shutdown() may be called for
QCA_ROME which does not have qcadev->bt_power assigned. Add a
NULL-pointer check before dereferencing the struct qca_power pointer.

Hi,

I just noticed we're still hitting this issue in mainline (saw it on the
mt8183-juniper platform in KernelCI). I see this commit was merged 6 days ago to
bluetooth-next, but it seems there wasn't a pull request with this fix yet to
include it in 6.11. I'm wondering if it's still going to be sent.

Thanks,
