Hi,
The driver gets the file location from the fex file, from "ctp_firmware".
There is no point having a standard location because the firmware device
can not be generic. There needs to be a different one for every hardware
configuration.

I have compiled the gslx680 driver, but there is a problem finding the
firmware file (Error -2). Is there an standard location where the
module will search for it?
I'm using a 3.4 kernel, and the F20 image. Many thanks!
