Subject: ide: ide-tape.c sparse annotations and unaligned access removal
X-Git-Tag: v2.6.27-rc1~509^2~11
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cd740ab0f69f6c94d9c7f916758e308f30a439fa;p=linux-2.6

ide: ide-tape.c sparse annotations and unaligned access removal

If this is actually unaligned the access of speed/max_speed above
is already broken and needs a get_unaligned.  Otherwise it is
aligned and they can be removed.
