EEPROM is read by ath9k regardless of whether debugging is enabled or
not.

Sorry, I haven't touched compat-wireless for a long time.

It means that CONFIG_ATH9K_DEBUG wasn't enabled.  If I enable it, I see
3 parameters:

parm:           debug:uint
parm:           nohwcrypt:Disable hardware encryption (int)
parm:           btcoex_enable:Enable Bluetooth coexistence support (bool)

It would load the module.  If you need any specific information, you can
just add a printk() statement in the place where the code is read.

That should work.
