From: Chatre, Reinette Date: Tue, 2 Dec 2008 20:14:05 +0000 (-0800) Subject: iwlwifi: store ucode version number X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c02b3acd29766c6f79c2411cb5b85e1ee72c4c8f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git iwlwifi: store ucode version number We store the ucode version number as part of iwl_priv/iwl3945_priv. This enables us to determine if particular ucode has support for features in order to have driver support more than one ucode API. Signed-off-by: Reinette Chatre Signed-off-by: John W.
