I've applied patches 4 and 9 on a recent -next, after fixing a conflict
due to patch 3 ("usb: musb_am335x: source cleanup"):

For these two patches, Tested-by: Ezequiel Garcia <>

Tested on a beaglebone with a mass storage USB device, module load/unload
works without issues. The module_get/put in the phy is now preventing the
musb_am335x driver unload, which seems to be the real cause of the issue
I reported. Thanks for providing a proper fix!
