From dfe21582ac5ebc460dda98c67e8589dd506d02cd Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka 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.
