Subject: ath10k: search DT for qcom,ath10k-calibration-variant
Board Data File (BDF) is loaded upon driver boot-up procedure. The right
bmi-board-id.
The problem, however, can occur when the (default) board data file cannot
-fulfill the vendor requirements and it is necessary to use a different
+fulfill with the vendor requirements and it is necessary to use a different
board data file.
This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
* bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U
