The problem happens when pre-cal data file is loaded using the userspace
helper on the QCA9984. I was only able to use the device when I (for a test)
used the pre-cal data as cal-data (file).
The EEPROM on the on the PCI device doesn't seem to be populated with a valid
pre-cal data. I've already tested it with a QCA9984 device which had pre-cal
data in the PCI device's EEPROM and this worked fine (without cal file and
without pre-cal file).

Worked fine for QCA4019 and QCA9888 - but I had no luck with QCA9984. The
error shown above it the only thing I get.
