I stumble on an interesting name space issue once more.

I admit that there can be also risks with my update suggestions
in similar ways to contributions from other software developers.

A specific function implementation exists which performs also input
parameter validation.
http://lxr.free-electrons.com/source/drivers/sh/clk/core.c#L291

Such variants might not fit to the functions au1100fb_drv_suspend()
and au1100fb_drv_resume().


Do you want that I send a reduced patch?
