[PATCH] tipar char driver: wrong timeout value

this patch (2.4 & 2.6) fixes a bug about the timeout value. The formula
used to calculate jiffies from timeout is wrong.
The new formula is ok and takes care of integer computation/rounding.
There is the same bug in the tiglusb.c module which will be fixed by another
patch.
