checkpatch: add test for long udelay
Holger reported:
: The macro udelay cannot handle large values because of loss-of-precision.
:
: IMHO udelay on ARM is broken, because it also cannot work with fast
: ARM processors (where bogomips >= 3355, which is in sight now). It's
: just not broken enough that someone did something against it ... so
: the current kludge is good enough.
Until then, warn on long udelay uses.
Also fix uses of $line that should have been $herecurr.
