usb: common: debug: Check non-standard control requests

2022-10-26T10:35:03+00:00

[ Upstream commit b6155eaf6b05e558218b44b88a6cad03f15a586c ]

Previously usb_decode_ctrl() only decodes standard control requests, but
it was used for non-standard requests also. If it's non-standard or
unknown standard bRequest, print the Setup data values.

usb: ulpi: Call of_node_put correctly

2022-02-16T11:56:34+00:00

commit 0a907ee9d95e3ac35eb023d71f29eae0aaa52d1b upstream.

of_node_put should always be called on device nodes gotten from
of_get_*. Additionally, it should only be called after there are no
remaining users. To address the first issue, call of_node_put if later
steps in ulpi_register fail. To address the latter, call put_device if
device_register fails, which will call ulpi_dev_release if necessary.

usb: ulpi: Move of_node_put to ulpi_dev_release

2022-02-16T11:56:34+00:00

commit 092f45b13e51666fe8ecbf2d6cd247aa7e6c1f74 upstream.

Drivers are not unbound from the device when ulpi_unregister_interface
is called. Move of_node-freeing code to ulpi_dev_release which is called
only after all users are gone.

usb: common: ulpi: Fix crash in ulpi_match()

2022-02-01T16:27:04+00:00

commit 2e3dd4a6246945bf84ea6f478365d116e661554c upstream.

Commit 7495af930835 ("ARM: multi_v7_defconfig: Enable drivers for
DragonBoard 410c") enables the CONFIG_PHY_QCOM_USB_HS for the ARM
multi_v7_defconfig. Enabling this Kconfig is causing the kernel to crash
on the Tegra20 Ventana platform in the ulpi_match() function.

The Qualcomm USB HS PHY driver that is enabled by CONFIG_PHY_QCOM_USB_HS,
registers a ulpi_driver but this driver does not provide an 'id_table',
so when ulpi_match() is called on the Tegra20 Ventana platform, it
crashes when attempting to deference the id_table pointer which is not
valid. The Qualcomm USB HS PHY driver uses device-tree for matching the
ULPI driver with the device and so fix this crash by using device-tree
for matching if the id_table is not valid.

Partially revert "usb: Kconfig: using select for USB_COMMON dependency"

2021-10-05T11:45:16+00:00

This reverts commit cb9c1cfc86926d0e86d19c8e34f6c23458cd3478 for
USB_LED_TRIG.  This config symbol has bool type and enables extra code
in usb_common itself, not a separate driver.  Enabling it should not
force usb_common to be built-in!

usb: otg-fsm: Fix hrtimer list corruption

2021-07-27T14:31:31+00:00

The HNP work can be re-scheduled while it's still in-fly. This results in
re-initialization of the busy work, resetting the hrtimer's list node of
the work and crashing kernel with null dereference within kernel/timer
once work's timer is expired. It's very easy to trigger this problem by
re-plugging USB cable quickly. Initialize HNP work only once to fix this
trouble.

 Unable to handle kernel NULL pointer dereference at virtual address 00000126)
