Merge tag 'driver-core-5.13-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH:
"Here are two driver fixes for driver core changes that happened in
5.13-rc1.
The clk driver fix resolves a many-reported issue with booting some
devices, and the USB typec fix resolves the reported problem of USB
systems on some embedded boards.
Both of these have been in linux-next this week with no reported
issues"

clk: Skip clk provider registration when np is NULL
usb: typec: tcpm: Don't block probing of consumers of "connector" nodes
