[PATCH 5.17 0416/1126] ASoC: msm8916-wcd-analog: Fix error handling in pm8916_wcd_analog_spmi_probe

From: Miaoqian Lin <linmq006@gmail.com>

[ Upstream commit 9ebd62d60edcd4d9c75485e5ccd0b79581ad3c49 ]

In the error handling path, the clk_prepare_enable() function
call should be balanced by a corresponding 'clk_disable_unprepare()'
call , as already done in the remove function.
