[PATCH 4.15 01/47] net: dsa: Fix dsa_is_user_port() test inversion

[Greg Kroah-Hartman]

4.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@xxxxxxxxx>


[ Upstream commit 5a9f8df68ee6927f21dd3f2c75c16feb8b53a9e8 ]

During the conversion to dsa_is_user_port(), a condition ended up being
reversed, which would prevent the creation of any user port when using
the legacy binding and/or platform data, fix that.

Fixes: 4a5b85ffe2a0 ("net: dsa: use dsa_is_user_port everywhere")
