| Message-ID | <uoWRc-43L-7@gated-at.bofh.it> |
4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stanislaw Gruszka <sgruszka@redhat.com>
commit 83ec489193894e52bd395eec470f4f7c4286d4a5 upstream.
Since commit 41977e86c984 ("rt2x00: add support for MT7620") we do not
initialize TX_PIN_CFG setting. This cause breakage at least on some
RT3573 devices. To fix the problem patch restores previous behaviour
for non MT7620 chips.
Fixes: 41977e86c984 ("rt2x00: add support for MT7620")
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1480829
