usb: ohci: Balance controller wakeup on cleanup

[PATCH 0/4] usb: ohci: Balance controller wakeup on cleanup

Posted by Myeonghun Pak 1 week, 3 days ago

These four independent fixes disable controller wakeup after HCD removal
in the DA8xx, S3C2410, SPEAr and ST drivers. DA8xx also needs the same
cleanup when notifier registration fails after the HCD is added.

This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
