From: Johannes Berg Date: Thu, 21 Jan 2010 14:09:28 +0000 (-0800) Subject: iwlwifi: move 3945 specific data into union X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee525d13f501baeaa33209620398adaf0a820629;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git iwlwifi: move 3945 specific data into union To be obviously correct, this patch only modifies 3945 files and the struct definition. A follow-up patch will create the AGN part of the union.
