commit: dfe21582ac5ebc460dda98c67e8589dd506d02cd From: Stanislaw Gruszka <[email protected]> Date: Wed, 1 Jun 2011 17:17:57 +0200 Subject: [PATCH] iwl4965: correctly validate temperature value
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.
