[PATCH] PCI/pwrctrl: Fix double cleanup on devm_add_action_or_reset() failure
From: Geert Uytterhoeven
Date: Wed Jun 04 2025 - 04:38:50 EST
When devm_add_action_or_reset() fails, it calls the passed cleanup
function. Hence the caller must not repeat that cleanup.
Replace the "goto err_regulator_free" by the actual freeing, as there
will never be a need again for a second user of this label.
Fixes: 75996c92f4de309f ("PCI/pwrctrl: Add pwrctrl driver for PCI slots")
