[PATCH 5.11 185/601] regulator: bd9576: Fix return from bd957x_probe()

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

[ 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")
