From 511c7b1baa8ae86dbcf83b8f489d39ff4b64a123 Mon Sep 17 00:00:00 2001 From: Alexandre TORGUE Date: Thu, 15 Sep 2016 18:42:38 +0200 Subject: [PATCH] serial: stm32: clock disabling management Keep the clock enabled at the end of stm32_init_port but disable it in stm32_serial_remove. Note that stm32_pm function is there to manage the clock at runtime.
