Dbii F52N-PRO mini pci device reports an invalid
regdomain. This card has been reported to work on
MikroTik's RouterOS but failed on Linux:
[ 14.320000] ath: EEPROM regdomain: 0xffff
[ 14.320000] ath: EEPROM indicates we should expect a country code
[ 14.320000] ath: invalid regulatory domain/country code 0xbfff
[ 14.320000] ath: Invalid EEPROM contents
[ 14.320000] ath9k 0000:00:12.0: Failed to initialize device
[ 14.330000] ath9k: probe of 0000:00:12.0 failed with error -22
With the patch the device works fine.
