[PATCH v2 net] net: ethernet: ti: am65-cpsw: Fix forever loop in cleanup code

Posted by Dan Carpenter 2 months ago

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")
