[PATCH 5.10 163/530] regulator: bd9576: Fix return from bd957x_probe()
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

From: Dan Carpenter <redacted>
[ Upstream commit 320fcd6bbd2b500923db518902c2c640242d2b50 ]
The probe() function returns an uninitialized variable in the success
path. There is no need for the "err" variable at all, just delete it.
Fixes: b014e9fae7e7 ("regulator: Support ROHM BD9576MUF and BD9573MUF")
