[PATCH 1/1] usb: misc: usbtest: add bulk queue test

The bulk queue tests are used to show 'best performance' for bulk transfer, we are often asked this question by users. The implementation is the same with iso test, that is queue request at interrupt completion, so we reuse the iso structures, and rename them as common one. It's result should be

[PATCH v2] usb: phy: msm: Unregister VBUS and ID events notifiers

Right now even if driver failed to probe extcon framework will still deliver its VBUS and ID events, which will lead to random exception codes. Fix this by removing VBUS and ID events notifiers when probe fail. Fixes: 591fc116f330 ("usb: phy: msm: Use extcon framework for VBUS and ID
