pinctrl_generic_free_groups(9)

🎀 NAME 🎀

okay bestie, welcome to pinctrl_generic_free_groups(9) from the Kernel API Manual ✨ This function is the cleanup moment: it removes all pin groups. No cap.

🌸 SYNOPSIS 🌸

void pinctrl_generic_free_groups (struct pinctrl_dev *pctldev );

🦋 ARGUMENTS 🦋

• pctldev — pin controller device. That’s the pin controller bestie you’re handing over.

💅 DESCRIPTION 💅

⚠️ Locking is your responsibility, bestie. Note that the caller must take care of locking. The function is not doing that part for you — iykyk.

The pinctrl groups are allocated with devm_kzalloc, so no need to free them here. Like, do not come for them in this function — devm_kzalloc already has that covered. 💖
