Subject: [PATCH v1 1/2] net:hns: annotate IO address space properly
Date: Thu, 10 Dec 2015 17:23:09 +0200	[thread overview]
Message-ID: <1449760990-111046-1-git-send-email-andriy.shevchenko@linux.intel.com> (raw)

Mark address pointer with __iomem in the IO accessors.

Otherwise we will get a sparse complain like following

.../hns/hns_dsaf_reg.h:991:36: warning: incorrect type in argument 1 (different address spaces)
.../hns/hns_dsaf_reg.h:991:36:    expected unsigned char [noderef] [usertype] <asn:2>*base
.../hns/hns_dsaf_reg.h:991:36:    got void *base
