phy: tegra: xusb: check return value of devm_kzalloc()

2023-07-19T14:21:58+00:00

[ Upstream commit 44faada0f38fc333d392af04c343b0e23f8f5d81 ]

devm_kzalloc() returns a pointer to dynamically allocated memory.
Pointer could be NULL in case allocation fails. Check pointer validity.
Identified with coccinelle (kmerr.cocci script).

phy: tegra: xusb: Clear the driver reference in usb-phy dev

2023-07-19T14:21:45+00:00

commit c0c2fcb1325d0d4f3b322b5ee49385f8eca2560d upstream.

For the dual-role port, it will assign the phy dev to usb-phy dev and
use the port dev driver as the dev driver of usb-phy.

When we try to destroy the port dev, it will destroy its dev driver
as well. But we did not remove the reference from usb-phy dev. This
might cause the use-after-free issue in KASAN.

phy: qcom-qmp-pcie-msm8996: fix init-count imbalance

2023-06-09T08:34:23+00:00

commit e42f110700ed7293700c26145e1ed07ea05ac3f6 upstream.

The init counter is not decremented on initialisation errors, which
prevents retrying initialisation.

Add the missing decrement on initialisation errors so that the counter
reflects the state of the device.

phy: qcom-qmp-combo: fix init-count imbalance

commit 9bf03a0cbd80a256bc1e1c4bcc80bc2b06b8b2b9 upstream.

The init counter is not decremented on initialisation errors, which
prevents retrying initialisation and can lead to the runtime suspend
callback attempting to disable resources that have never been enabled.

Add the missing decrement on initialisation errors so that the counter
reflects the state of the device.
