# [PATCH] USB: Oops patch for 2.4.19-rc1, ohci
# 
# It fixes an oops some folk have reported, mostly with ISO on
# slow/busy CPUs, caused by an endpoint being on the schedule
# in a "never used" state.  I think of those four lines of
# code as a broken micro-optimization, which sometimes makes
# the host controller deliver bogus TDs back to the driver,
# which will then oops in its IRQ handler.
