From ec03ab77cc2c39d115118fcd4fc11a5801cbb70e Mon Sep 17 00:00:00 2001 From: Wilfried Klaebe Date: Tue, 25 Mar 2014 17:59:39 +0000 Subject: [PATCH] staging: rtl8188eu: remove spaces, correct counts to unbreak P2P ioctls staging: rtl8188eu: remove spaces, correct counts to unbreak P2P ioctls It looks like someone did a search-and-replace on that driver, putting spaces before "=" characters, without checking this is OK everywhere. Also, in some places, there's memcpm()s/strncmp()s checking for some different length than the fixed string argument. These things result in code not working as intended. Fix that.
