Subject: WARNING in module rt2870sta stable kernel 2.6.37
Hi, the following message was logged on a 2.6.37 kernel(it says
tainted, but it's actually a micro patch I wrote and applied on top of
current 2.6.37 vanilla, patch appended, but it should be irrelevant, I
just shut up a bunch of useless debug output for this staging driver):
