Subject: [PATCH 1/5] Fixes and clean up of code
Date: Fri, 13 Jun 2014 20:14:05 +0530 [thread overview]
Message-ID: <1402670645-8853-1-git-send-email-jahnavi.meher@gmail.com> (raw)
Changed the SDIO interrupt type variables according to changes
in firmware, made fixes to auto rate code and radio-caps frame,
added defines for endpoints and some other minor fixes.
