From 872907bb17fe2d8d01d0e9723f72f91cb4ea103f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 6 Jun 2011 09:41:15 -0700 Subject: [PATCH] iwlagn: don't check ucode subtype The ucode subtypes keep changing, and there's no particular reason to be checking them (other than a paranoid sanity check). Since the numbers are also in conflict between different ucode images now, simply don't check them any more and rely on the images being built correctly. Also, to indicate that, rename the constants and the enum, moving it to a different file.
