device_is_dependent(9)
π device_is_dependent(9) π
okay bestie, welcome to the Kernel API Manual β¨ this one's a lil device_is_dependent(9) page and it's genuinely so much simpler than it looks, i promise π«Ά
πΈ NAME πΈ
device_is_dependent β literally just checks if one device depends on another one π
β¨ SYNOPSIS β¨
int device_is_dependent (struct device *dev , void *target );
like that's it. that's the whole vibe check π
π ARGUMENTS π
devβ the device you're checking dependencies for, aka the main character πtargetβ the device you're checking against, the one we're like "do u depend on her??" about π
π¦ DESCRIPTION π¦
so here's the tea: this checks if target depends on dev, or on any device dependent on it β that's its child, or its consumer, etc. etc. like the whole little dependency tree of girlies π
it returns 1 if that's the case, or 0 otherwise. nosy but honest. not me checking the dependency graph like it's someone's instagram followers π

ok that's a LOT of friends but they're all slaying in their own lanes, go read them too if u want the full lore ππ
and that's a wrap, bestie π this page lives in ./drivers/base, dated October 2026, and yes she ate π
β¨ bye love u π«Ά
