Subject: [PATCH] rtc: mxc_v2: Add missing clk_disable_unprepare()
Git-commit: 55d5a86618d3b1a768bce01882b74cbbd2651975
Patch-mainline: v6.2-rc1
References: git-fixes

The call to clk_disable_unprepare() is left out in the error handling of
devm_rtc_allocate_device. Add it back.

Fixes: 5490a1e018a4 ("rtc: mxc_v2: fix possible race condition")
