Subject: usb: typec: qcom: Update the logic of regulator enable and disable
From: Hui Liu <quic_huliu@xxxxxxxxxxx>
commit 76750f1dcad3e1af2295cdf2f9434e06e3178ef3 upstream.
Removed the call logic of disable and enable regulator
in reset function. Enable the regulator in qcom_pmic_typec_start
function and disable it in qcom_pmic_typec_stop function to
avoid unbalanced regulator disable warnings.
Fixes: a4422ff22142 ("usb: typec: qcom: Add Qualcomm PMIC Type-C driver")
