Subject: coresight: Use PTR_ERR_OR_ZERO()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3703221944d00ac7af85c293f8939a273f587544;p=linux.git

coresight: Use PTR_ERR_OR_ZERO()

Fix ptr_ret.cocci warnings:
drivers/hwtracing/coresight/coresight-tpiu.c:163:1-3: WARNING: PTR_ERR_OR_ZERO can be used
drivers/hwtracing/coresight/coresight-funnel.c:217:1-3: WARNING: PTR_ERR_OR_ZERO can be used
drivers/hwtracing/coresight/coresight-dynamic-replicator.c:166:1-3: WARNING: PTR_ERR_OR_ZERO can be used

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR
