Date: Mon, 24 Jan 2022 19:45:51 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Robert Hancock <robert.hancock@...ian.com>, Stephen Boyd <sboyd@...nel.org> Subject: [PATCH 5.16 0962/1039] clk: si5341: Fix clock HW provider cleanup From: Robert Hancock <robert.hancock@...ian.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.
