From e065ddb891755c74f73c60989f96784f3aa65f81 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Tue, 26 May 2015 06:34:27 -0700 Subject: [PATCH] mwifiex: fix SDIO firmware dump problem It's been observed that firmware doesn't go back to normal state when all firmware memories are dumped. As a result, further commands are blocked. This happens due to missing driver change of writing READ DONE to control register for SDIO interface. This patch adds a missing change to fix the problem.
