'ATH10K driver <-> 10.4 firmware' expects cal data to be either in
EEPROM or pre-cal-file or DT.
Hope the error is observed when there is no cal data loaded.
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).

Do you mean this patch works for only QCA4019 and not working for
QCA9984 ?
Worked fine for QCA4019 and QCA9888 - but I had no luck with QCA9984.
The
error shown above it the only thing I get.
I tested this on QCA9984 and it worked with below config,

Kindly try with the latest firmware from Kalle's git mentioned above.
