devm_clk_hw_register(9)

💖 devm_clk_hw_register(9) 💖

okay so we're in the Kernel API Manual, bestie, and today's main character is devm_clk_hw_register. it's giving "clock registration but make it managed," and honestly? iconic. 🎀

🌸 NAME 🌸

devm_clk_hw_register — resource managed clk_hw_register(). slay. ✨

✨ SYNOPSIS ✨

int devm_clk_hw_register (struct device *dev , struct clk_hw *hw );

💅 ARGUMENTS 💅

• dev — the device that's registering this clock, fr fr.
• hw — link to hardware-specific clock data. that's the vibe. 🦋

🦋 DESCRIPTION 🦋

Managed clk_hw_register. Clocks registered by this function are automatically clk_hw_unregistered on driver detach. See clk_hw_register for more information.

okay so lowkey the whole point is that this is the managed version: when the driver detaches, the unregistering happens automatically. no cap. 🌈
