platform_get_irq_byname(9) 🦋

okay so welcome to the Kernel API Manual, bestie — this page is literally all about platform_get_irq_byname, and it's giving main character energy in the platform-device friend group. No cap, it's short and sweet. 💅

✨ NAME ✨

platform_get_irq_byname — get an IRQ for a device by name

🌸 SYNOPSIS 🌸

int platform_get_irq_byname (struct platform_device *dev , const char
*name );

🎀 ARGUMENTS 🎀

• dev — platform device
• name — IRQ name

💅 DESCRIPTION 💅

Okay so it gets an IRQ exactly like platform_get_irq does, but then by name rather than by index. That's the whole plot. The way that name-based lookup ate and left no crumbs — obsessed. 🫶

🔥 RETURN 🔥

On success, you get a non-zero IRQ number; on failure, you get a negative error number. That's the vibe check, fr fr. 💖
