From 18bf965702058f5f8039e6a46bb5ebaa18d38ebd Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Wed, 6 Apr 2011 16:46:55 -0700 Subject: [PATCH] mwifiex: fix cmd_skb headroom decreasing issue Before calling host_to_card() to send the cmd to firmware, we use skb_push() to add 4 bytes SDIO interface header at the start of the data buffer. Since cmd_skb data structure will be re-used at a later time, we need to restore its headroom by removing the 4 bytes header.
