usb: ulpi: Call of_node_put correctly

2022-01-31T13:11:20Z

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

2022-01-31T13:11:16Z

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()

2022-01-26T12:42:05Z

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.

USB: common: debug: add needed kernel.h include

2022-01-05T15:20:27Z

drivers/usb/common/debug.c was only including one usb .h file, which would then accidentally drag in other .h files that were really needed. Fix up the implict dependancy by correctly adding kernel.h to the file. Signed-off-by: Greg Kroah-Hartman

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

2021-10-05T11:45:16Z

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

2021-07-27T14:31:31Z

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.
