Porting to Linux version 4.4.8

[rueichang]

Hello everyone,
I'm recently porting the QCA9377 with SDIO in ARM-based Linux. After porting linux-ath's ath10k to my source code. I found there is a lot of incompatible functions and macro between my source code and linux-ath. My Linux version is 4.4.8.

Does linux-ath have minimum version requirement of Linux? I'm afraid that my Linux version is older than yours so that I can't use your source code directly.

Already fixed incompatible issue on kernel 4.4
