From 6d1b80fd886937ad4d6169ffa78cb0075eebce53 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Tue, 19 Feb 2013 05:18:50 +0100 Subject: [PATCH] staging/slicoss: Fix operation may be undefined warning gcc complains about an undefined operation: slicoss.c:1417:19: warning: operation on 'rspq->pageindex' may be undefined [-Wsequence-point] The intended operation was (probably) to retrieve the pageindex + 1 and let it wrap around if it reaches the num_pages.
