From be80ae3d799dab1b46c661158b2b5d6695258178 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 31 Dec 2022 09:10:17 +0100 Subject: watchdog: bcm7038: 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().
