Subject: [PATCH] wifi: ath12k: Introduce and use ath12k_sta_to_arsta()
Currently, the logic to return an ath12k_sta pointer, given a
ieee80211_sta pointer, uses typecasting throughout the driver. In
general, conversion functions are preferable to typecasting since
using a conversion function allows the compiler to validate the types
of both the input and output parameters.
ath12k already defines a conversion function ath12k_vif_to_arvif() for
a similar conversion. So introduce ath12k_sta_to_arsta() for this use
case, and convert all of the existing typecasting to use this
function.
