Agreed.  I put this off some time back, but I figured the WM831X
driver would bring the issue back up.

I'm happy for the core to concatenate the strings when a struct device
*dev is passed in.  However the reason I dropped this in the first
place is that I have some ideas on providing something like clk_get
directly from the common clk core and I hadn't figured out all of the
details yet.  For now we can handle the string concatenation in the
core and figure out those tricky details if/when the time comes to
provide a clk_get which is more closely linked to the clock framework
implementation.

I'll roll in a patch for my fixes series.

Mike
