From 9dc2aa96a3533215fbed9cf1297f7aa70dae840b Mon Sep 17 00:00:00 2001 From: Li Zetao Date: Wed, 23 Aug 2023 21:39:23 +0800 Subject: spi: davinci: Use helper function devm_clk_get_enabled() Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be replaced by devm_clk_get_enabled() when driver enables (and possibly prepares) the clocks for the whole lifetime of the device. Moreover, it is no longer necessary to unprepare and disable the clocks explicitly.
