+Subject: [PATCH 2/2] rt2800: do VCO calibration after programming ALC
+To: Stanislaw Gruszka <sgruszka@redhat.com>
+Cc: Helmut Schaa <helmut.schaa@googlemail.com>,
+    linux-wireless@vger.kernel.org,
+    Kalle Valo <kvalo@codeaurora.org>
+
+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.
