Subject: [23/89] iwl4965: correctly validate temperature value
2.6.39-stable review patch. If anyone has any objections, please let us know.
------------------
From: Stanislaw Gruszka <sgruszka@...hat.com>
commit dfe21582ac5ebc460dda98c67e8589dd506d02cd upstream.
In some cases we can read wrong temperature value. If after that
temperature value will not be updated to good one, we badly configure
tx power parameters and device is unable to send a data.
