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: drivers/telephony/ixj.c: In function `add_caps': drivers/telephony/ixj.c:5930:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:5950:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:5954:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:5965:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:5976:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:5988:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:5998:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6003:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6008:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6013:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6019:38: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6026:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6031:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6036:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6041:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6049:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6057:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6065:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] drivers/telephony/ixj.c:6071:39: warning: operation on `j->caps' may be undefined [-Wsequence-point] Signed-off-by: Uwe Kleine-König <uwe@kleine-koenig.org> Cc: Lucas De Marchi <lucas.demarchi@profusion.mobi> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
