Subject: IB/core: Use PTR_ERR_OR_ZERO()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f4cd9d588e77c86362ba3c072385cde11c86b611;p=linux.git

IB/core: Use PTR_ERR_OR_ZERO()

Fix ptr_ret.cocci warnings:
drivers/infiniband/core/uverbs_cmd.c:1156:1-3: WARNING: PTR_ERR_OR_ZERO can be used

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