Daniel Golle 3d71d1d9a9 mac80211: rt2x00: reorder patches and prepare for MT7620 external PA
Import change to make external PA capability consistent with the
vendor driver instead of having the logic inverted.
While at it, apply patches in the same order as they got merged
upstream.

Subject: [PATCH 2/2] rt2800: do VCO calibration after programming ALC
To: Stanislaw Gruszka <sgruszka@redhat.com>

Scanning fails if we don't do VCO calibration every time.
The vendor driver duplicates the VCO calibration function into the
channel switching logic, we can do the same with less duplication.
