[PATCH 3.14 023/228] iwlwifi: mvm: avoid searching unnecessary columns

From: Greg Kroah-Hartman
Date: Wed Jun 04 2014 - 20:46:53 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Eyal Shapira <eyal@xxxxxxxxxx>

commit d8fff919ecd7820084675c2814913445e95640ac upstream.

Don't search columns which are unlikely to succeed as previous
columns searched with less aggressive modulation failed.
