acpi_device_dep(9)

✨ NAME ✨

okay so bestie, lemme introduce you to acpi_device_dep — the little kernel function (it's acpi_device_dep(9) in the Kernel API Manual, iykyk) that checks ACPI device dependency 💅

🦋 SYNOPSIS 🦋

bool acpi_device_dep (acpi_handle target , acpi_handle match );

🎀 ARGUMENTS 🎀

• target — the ACPI handle of the target ACPI device. like, the one we're snooping on 🕵️‍♀️
• match — the ACPI handle we're looking up in target's _DEP list. the one we're hunting for 💖

🔥 DESCRIPTION 🔥

Returns true if match is present in the list returned by _DEP for target, or false otherwise. that's it, that's the whole vibe check — does this handle slay in the dependency list or not 👑

not me being obsessed with how simple that is. periodt 💜
