Miller" <davem@...emloft.net> Subject: [PATCH 5.4 001/147] net: dsa: Do not make user port errors fatal From: Florian Fainelli <f.fainelli@...il.com> commit 86f8b1c01a0a537a73d2996615133be63cdf75db upstream. Prior to 1d27732f411d ("net: dsa: setup and teardown ports"), we would not treat failures to set-up an user port as fatal, but after this commit we would, which is a regression for some systems where interfaces may be declared in the Device Tree, but the underlying hardware may not be present (pluggable daughter cards for instance).
