[PATCH 0/6] usb: add missing pm_runtime_dont_use_autosuspend() calls

Posted by Joshua Crofts 1 week, 2 days ago

Several drivers in the USB subsystem forget to call dont_use_autosuspend()
on teardown or error, causing potential resource leaks. This series adds
the missing calls.

The offending drivers were found using a semantic patch for Coccinelle
I'm working on [1].
