Subject: [SCSI] hpsa: use ioremap_nocache instead of ioremap
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=088ba34c92055547ef4cc862a863334c01d9a304;p=linux-beck.git

[SCSI] hpsa: use ioremap_nocache instead of ioremap

I think ioremap() ends up being equivalent to ioremap_nocache
by default, but we should signal our intent that these mappings
should be non-cacheable.
