add "ath9k: Avoid OF no-EEPROM quirks without qca, no-eeprom" to 4.14- and 4.19-stable releases

Hello,

please add this patch:

Subject: ath9k: Avoid OF no-EEPROM quirks without qca,no-eeprom Author: Daniel F. Dickinson cshored@thecshore.com commit ce938231bd3b1d7af3cbd8836f084801090470e1 [0]

to the stable release of 4.14 and 4.19.

The patch fixes a problem with bog-standard (as in consumer-grade) ath9k pci cards that are defined in DeviceTrees. In the current context, the driver handles those cards as special-basket cases that need off-card calibration data in order to work.

Regards, Christian
