Subject: [PATCH] scatterlist.h: Change CONFIG_DEBUG_SG for ifdef statement in sg_set_bf
Date: Sat, 2 Aug 2014 22:56:13 -0400 [thread overview]
Message-ID: <1407034573-14358-1-git-send-email-xerofoify@gmail.com> (raw)
This changes the ifdef statement in sg_set_bg to !CONFIG_DEBUG_SG in order
to avoid a bug with xhci dequence/enquence functions.
