[PATCH net] net: ethernet: ti: am65-cpsw: Fix forever loop in cleanup code

From: Dan Carpenter <hidden>
Date: 2024-09-26 09:50:51
Also in: kernel-janitors, lkml
Subsystem: networking drivers, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

This error handling has a typo.  It should i++ instead of i--.  In the
original code the error handling will loop until it crashes.

Fixes: da70d184a8c3 ("net: ethernet: ti: am65-cpsw: Introduce multi queue Rx")
Signed-off-by: Dan Carpenter <redacted>
