Subject: [PATCH] PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe()
Git-commit: 6049aae52392539e505bfb8ccbcff3c26f1d2f0b
Patch-mainline: v6.2-rc5
References: git-fixes

If an error occurs after a successful pm_genpd_init() call, it should be
undone by a corresponding pm_genpd_remove().

Add the missing call in the error handling path, as already done in the
remove function.

Fixes: bf6910abf548 ("power: avs: Add support for CPR (Core Power Reduction)")
