okay so this is priv_to_wiphy(9) from the Kernel API Manual, and honestly? she's a short queen and she knows it π
π NAME π
priv_to_wiphy β returns the wiphy that contains the priv, bestie. that's it. that's the whole job π«Ά
πΈ SYNOPSIS πΈ
struct wiphy * priv_to_wiphy (void *priv );
π¦ ARGUMENTS π¦
privβ a pointer that was previously returned bywiphy_priv. like, the whole bit is that you already got this thing out ofwiphy_privand now you're going the other way. iykyk π§
β RETURN β
The wiphy of priv, periodt. that's what you get back π no cap, no surprises.
and yeah, that's genuinely the entire first chunk β more coming, don't go anywhere π
