Lwazi Dube e2083354f1 arch/arm/sama5: Use a recursive mutex to fix OHCI deadlock. ... Unplugging a USB device from an OHCI root hub will cause a deadlock if DRVR_EPFREE is called from sam_rhsc_bottomhalf. A typical call chain looks like this: sam_rhsc_bottomhalf-> CLASS_DISCONNECTED->usbhost_destroy->DRVR_EPFREE. In this case DRVR_EPFREE tries to lock a locked mutex. A recursive mutex prevents this deadlock.		2023-05-03 12:53:30 +08:00
