Sinan Kaya b1391a5bf8 scsi: mpt3sas: remove redundant wmb ... Due to relaxed ordering requirements on multiple architectures, drivers are required to use wmb/rmb/mb combinations when they need to guarantee observability between the memory and the HW. The mpt3sas driver is already using wmb() for this purpose. However, it issues a writel following wmb(). writel() function on arm/arm64 arhictectures have an embedded wmb() call inside. This results in unnecessary performance loss and code duplication. writel already guarantees ordering for both cpu and bus. we don't need additional wmb() Signed-off-by: Sinan Kaya <okaya@codeaurora.org> Acked-by: Sreekanth Reddy <sreekanth.reddy@broadcom.com> Reviewed-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Martin K.
