From: Dominik Brodowski Date: Sat, 20 Mar 2010 18:39:26 +0000 (+0100) Subject: pcmcia: dev_node removal (drivers with unregister_netdev check) X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c7c2fa07;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git pcmcia: dev_node removal (drivers with unregister_netdev check) As a third step, remove any usage of dev_node_t from drivers which only wrote to this typedef/struct, except to determine whether register_netdev() succeeded previously. However, the function calling unregister_netdev() was only ever called by the PCMCIA core if register_netdev() succeeded previously. The lonely exception was easily fixed.
