Subject[PATCH 5.4 294/320] clk: si5341: Fix clock HW provider cleanup
Date
From: Robert Hancock <robert.hancock@calian.com>

commit 49a8f2bc8d88702783c7e163ec84374e9a022f71 upstream.

The call to of_clk_add_hw_provider was not undone on remove or on probe
failure, which could cause an oops on a subsequent attempt to retrieve
clocks for the removed device. Switch to the devm version of the
function to avoid this issue.

Fixes: 3044a860fd09 ("clk: Add Si5341/Si5340 driver")
