From cc75c577806a53893122829d91cb122b51643a2d Mon Sep 17 00:00:00 2001 From: Xinming Hu Date: Wed, 14 Dec 2016 19:40:51 +0530 Subject: [PATCH] mwifiex: get rid of global save_adapter and sdio_work This patch moves sdio_work to card structure, in this way we can get adapter structure in the work, so save_adapter won't be needed.
