Some drivers use sprintf to build clk connection id names but the clk
core will save those strings and occasionally print them back. Duplicate
the con_id strings instead of fixing all the users.

Some examples of using sprintf for con_id include:
drivers/mfd/omap-usb-host.c
drivers/tty/serial/samsung.c
sound/soc/fsl/fsl_asrc.c
There are lots more. They are difficult to find and "fixing" them on the
consumer side requires nasty code to keep track of the allocated clkname.
