From 6a1fe83bf14b87fd8b02f391ea629f69624d9c34 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sat, 1 Aug 2020 13:48:20 +0800 Subject: [PATCH] regulator: qcom_spmi: Improve readability for setting up enable/mode pin control By checking data->pin_ctrl_enable / data->pin_ctrl_hpm flags first, then use switch-case to improve readability.
