drivers/staging/telephony/ixj.c: fix warning about sequence points
In the statement
j->caplist[j->caps].handle = j->caps++;
there is no sequence point between the usage of j->caps on the LHS of
the assignment and the incrementation on its RHS. So it's not defined
in Standard C if j->caps is already incremented when used on the LHS
even though the postfix ++ operator is used. To properly fix that the
incrementation has to be done in a separate expression.
This fixes:
