From: Dominik Brodowski Date: Mon, 14 Nov 2005 20:25:35 +0000 (+0100) Subject: [PATCH] pcmcia: remove dev_list from drivers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b463581154f3f3eecda27cae60df813fefcd84d3;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [PATCH] pcmcia: remove dev_list from drivers The linked list of devices managed by each PCMCIA driver is, in very most cases, unused. Therefore, remove it from many drivers.
