From 0a03207205f95abd90c8e1abb00c158066560ed2 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 31 Dec 2022 11:37:39 +0100 Subject: [PATCH] watchdog: davinci: Use devm_clk_get_enabled() helper The devm_clk_get_enabled() helper: - calls devm_clk_get() - calls clk_prepare_enable() and registers what is needed in order to call clk_disable_unprepare() when needed, as a managed resource. This simplifies the code and avoids the need of a dedicated function used with devm_add_action_or_reset().
