That would be great IMHO.

I think, I prefer module options instead of platform_data. Those can be
specified by /etc/modprobe.d/file (or /etc/modprobe.conf) or by kernel
command line parameters in bootloader, for example:

rt2x00lib.disable_5ghz=1 rt2800pci.eeprom_file=1

But, module options are limited to one device, so if there is or will be
possible to have two or more rt2x00 devices on one system with different
options, platform data should be used.

Thanks
