Revert "mac80211: warn when receiving frames with unaligned data"
This reverts commit 81100eb80add328c4d2a377326f15aa0e7236398 for the release, to avoid the unnecessary warning noise that is only really relevant to wireless driver developers. The warning will probably go right back in after I cut the release, but at least we won't unnecessarily worry users. Acked-by: John W. Linville <linville@tuxdriver.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
