Absolutely right...

Because it's a connection ID, not a clock _name_.  I see that we're still
making all the same mistakes with clocks that were made years ago, and
which lead down the path of amazingly complex drivers having conditional
clock names and the like.

Is there a reason why you can't split this into separate device and input
names, and use clk_get_sys() rather than passing NULL as the device to
clk_get().  This is exactly why we've ended up with clk_get_sys(), to
cater for the cases where there is no struct device to associate with the
connection ID: the idea behind clk_get_sys() is that you pass the device
name explicitly, along with the connection ID.
