Subject: scsi: mpi3mr: Drop unnecessary volatile from __iomem pointers
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6853885b21cb1d7157cc14c9d30cc17141565bae;p=thirdparty%2Fkernel%2Flinux.git

scsi: mpi3mr: Drop unnecessary volatile from __iomem pointers

The volatile qualifier is redundant for __iomem pointers.

Cleaned up usage in mpi3mr_writeq() and sysif_regs pointer as per
Upstream compliance.
