From a649136b17af6361355874a10e9219390c266a2c Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Sat, 31 Jul 2021 22:50:33 +0300 Subject: PM: runtime: add devm_pm_clk_create helper A typical code pattern for pm_clk_create() call is to call it in the _probe function and to call pm_clk_destroy() both from _probe error path and from _remove function. For some drivers the whole remove function would consist of the call to pm_remove_disable(). Add helper function to replace this bolierplate piece of code. Calling devm_pm_clk_create() removes the need for calling pm_clk_destroy() both in the probe()'s error path and in the remove() function.
