Since commit 4f9edd2d7e8d "usb: musb: Fix the crash issue during reboot"
musb_shutdown() does pm_runtime_get_sync/pm_runtime_put by itself, so
this no longer needs to be done by the caller. Also, musb_exit_debugfs()
doesn't access the device, so just drop those runtime_pm calls.

I don't understand what is the relationship with 4f9edd2d7e8d and
musb_shutdown(), it seems this patch is basically reverting
4f9edd2d7e8d.

Cheers.

No it's not, read my patch and it's description again. 4f9edd2d7e8d is
patching musb_shutdown(), mine musb_remove().
