PATCH 1/1 compat-wireless: Handle name change from iwlagn to iwlwifi in 3.2

From: Don Fry <[email protected]>

With linux-3.2 the iwlagn driver is renamed iwlwifi. For some kernels (like 3.1.5) this causes the non-compat iwlagn.ko to try and run against the compat mac80211 resulting in an oops. This change prevents the non-compat iwlagn.ko from being loaded.

Applied and pushed, thanks!
