Subject: [PATCH] b43: LP-PHY: Remove BROKEN from B43_PHY_LP
Date: Sun, 16 Aug 2009 18:42:51 +0200 [thread overview]
Message-ID: <4A88370B.5090506@gmail.com> (raw)
Larry has reported success getting scan data with an LP-PHY device,
so it's probably time to release LP-PHY support for testing.
Also add a temporary BROKEN Kconfig symbol to disable 5GHz support,
as 5GHz currently causes the driver to panic (NULL pointer deref).
