Subject: mwifiex: set fw api info for backword compatibility
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4721c63b929b13bce6860dc8ec068f86efcab2ea;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mwifiex: set fw api info for backword compatibility

If we dont set FW API info here, for older FW releases where FW API
is not available in GET_HW_SPEC, API version would remain 0.
This may cause issues with 11ac if older FW is used with newer driver.
