rpm_regulator_init_vreg(9)

✨ NAME ✨

okay so bestie, this is rpm_regulator_init_vreg from the Kernel API Manual, and it does exactly what it says on the tin: it initializes all the attributes of a qcom_smd-regulator. no cap, that’s the whole vibe. 🎀

🌸 SYNOPSIS 🌸

int rpm_regulator_init_vreg (struct qcom_rpm_reg *vreg , struct device *dev , struct device_node *node , const struct rpm_regulator_data *pmic_rpm_data );

it’s giving “one function, four pointers, let’s get this regulator set up” energy. 💅

🦋 ARGUMENTS 🦋

• vreg — pointer to the individual qcom_smd-regulator resource. this is the lil regulator bestie getting its attributes initialized. 🫶
• dev — pointer to the top level qcom_smd-regulator PMIC device. the main character device, basically. 👑
• node — pointer to the individual qcom_smd-regulator resource device node. very “this specific resource’s paperwork” of it. 📄
• pmic_rpm_data — pointer to a null-terminated array of qcom_smd-regulator resources defined for the top level PMIC device. yes, null-terminated — the array knows when to stop, iconic behavior honestly. ✨

💖 RETURN 💖

• 0 on success. slay. 🎉
• a negative error number on failure. so if it’s not giving success, it’s giving a negative error number, fr fr. 😭

no vague “something went wrong” here — you get a negative error number and you deal with it. periodt.
