msi_device_destroy_sysfs(9)

💅 msi_device_destroy_sysfs(9) — Kernel API Manual, bestie ✨

okay so this is the msi_device_destroy_sysfs(9) page from the Kernel API Manual, and it's literally the cleanup girlie for MSI sysfs entries. no cap.

🌸 NAME 🌸

Destroy msi_irqs sysfs entries for a device. that's the whole assignment, and she ate 💅

✨ SYNOPSIS ✨

void msi_device_destroy_sysfs (struct device *dev );

yeah, that's the signature: void return, one struct device *dev argument. very main-character energy, lowkey.

🎀 ARGUMENTS 🎀

• dev — the device (PCI, platform etc) for which to remove sysfs entries. this is the one whose sysfs entries are getting removed, periodt.
