regulator_lock_dependent(9)

🌸 regulator_lock_dependent(9) 🌸

💖 NAME 💖

Bestie, this is regulator_lock_dependent from the Kernel API Manual — the function that locks a regulator's suppliers and coupled regulators. No cap, that's the whole assignment. 💅

✨ SYNOPSIS ✨

void regulator_lock_dependent (struct regulator_dev *rdev , struct ww_acquire_ctx *ww_ctx );

🎀 ARGUMENTS 🎀

• rdev — regulator source. That's the regulator we're starting from, bestie. 🫶
• ww_ctx — w/w mutex acquire context. Yep, the w/w mutex acquire context — it's giving lock-order realness. 🔒

🦋 DESCRIPTION 🦋

Okay so this function is literally a wrapper on regulator_lock_recursive, and what it does is lock all regulators related with rdev by coupling or supplying. That's it, that's the vibe: related regulators get locked together, and the function is doing the wrapper thing around regulator_lock_recursive. Iconic. 💖✨

Okay that's the whole page, bestie — this cutie is from the ./drivers/regulator source, dated October 2026, and the page title is regulator_lock_dependent(9) in the Kernel API Manual. Bye bestie, go slay those regulator locks! 💅🎀✨
