Subject: [PATCH 5.15 726/917] rtc: rv3032: fix error handling in rv3032_clkout_set_rate()

From: Dan Carpenter <dan.carpenter@...cle.com>

[ Upstream commit c3336b8ac6091df60a5c1049a8c685d0b947cc61 ]

Do not call rv3032_exit_eerd() if the enter function fails but don't
forget to call the exit when the enter succeeds.
