[PATCH net-next v3 2/4] stmmac: loongson: Remove surplus loop

From: Philipp Stanner <phasta@kernel.org>
Date: 2025-02-24 13:53:41
Also in: linux-arm-kernel, lkml
Subsystem: networking drivers, stmmac ethernet driver, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

loongson_dwmac_probe() contains a loop which doesn't have an effect,
because it tries to call pcim_iomap_regions() with the same parameters
several times. The break statement at the loop's end furthermore ensures
that the loop only runs once anyways.

Remove the surplus loop.
