From: Michael Buesch Date: Wed, 12 Dec 2007 21:05:18 +0000 (+0100) Subject: b43: Fix for broken transmission X-Git-Tag: v2.6.25-rc1~1162^2~446 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=38d1b4ce901506729f6c7f9a14f02f4327c577cc;p=platform%2Fkernel%2Flinux-3.10.git b43: Fix for broken transmission This patch fixes the transmission problems introduced by commit f04b3787bbce4567e28069a9ec97dcd804626ac7 I'm not sure if the dummy read is really required. The old code does it. I think it can't hurt and can possibly fix some write posting problems (hardware bugs or whatever. Who knows). Signed-off-by: Michael Buesch Signed-off-by: John W.
