[PATCH 36/41] usb: gadget: omap_udc: Make it CCF clk API compatible

[Arnd Bergmann]

From: Janusz Krzysztofik <jmkrzy...@gmail.com>

The driver, OMAP1 specific, now omits clk_prepare/unprepare() steps, not
supported by OMAP1 custom implementation of clock API.  However, non-CCF
stubs of those functions exist for use on such platforms until converted
to CCF.

Update the driver to be compatible with CCF implementation of clock API.
