Subject: [PATCH 2/2] rt2800: do VCO calibration after programming ALC
|
|
To: Stanislaw Gruszka <sgruszka@redhat.com>
|
|
Cc: Helmut Schaa <helmut.schaa@googlemail.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.
