Can you pass the musb device pointer available in the same file? Also, da850_clks[] in da850.c needs to be fixed to add the matching device name.
This clock can be used for usb 1.1 PHY even when musb is not being used, so I don't think we can depend on having a musb device here.
Also, in a previous review, it was decided that the usb clocks should *not* be added to da850_clks[] [1]. Instead, they are dynamically registered elsewhere.
