Subject: bfa: fix compilation warning and endianness issues in powerpc
From: Jing Huang <huangj@xxxxxxxxxxx>
Fix the compilation warning in powerpc:
drivers/scsi/bfa/bfa_ioc.c: In function 'bfa_ioc_msgget':
drivers/scsi/bfa/bfa_ioc.c:1331: warning: value computed is not used
drivers/scsi/bfa/bfa_ioc_ct.c: In function 'bfa_ioc_ct_notify_hbfail':
drivers/scsi/bfa/bfa_ioc_ct.c:177: warning: value computed is not used
drivers/scsi/bfa/bfa_ioc_ct.c:180: warning: value computed is not used
drivers/scsi/bfa/bfa_ioc_ct.c: In function 'bfa_ioc_ct_pll_init':
drivers/scsi/bfa/bfa_ioc_ct.c:381: warning: value computed is not used
drivers/scsi/bfa/bfa_ioc_ct.c: In function 'bfa_ioc_ct_ownership_reset':
drivers/scsi/bfa/bfa_ioc_ct.c:421: warning: value computed is not used
drivers/scsi/bfa/bfa_ioc_cb.c: In function 'bfa_ioc_cb_notify_hbfail':
drivers/scsi/bfa/bfa_ioc_cb.c:99: warning: value computed is not used
drivers/scsi/bfa/bfa_ioc_cb.c: In function 'bfa_ioc_cb_ownership_reset':
drivers/scsi/bfa/bfa_ioc_cb.c:272: warning: value computed is not used
The same change also fixes endian issues we found in powerpc test. I
remove an unnecessary word swap in bfa_os_reg_read() and
bfa_os_reg_write() because the kernel provided readl and writel are
already doing so. The compilation warning also goes away after this
change. For bfa_os_mem_read() and bfa_os_mem_write() macros, I add a swap
since these two macros are designed to read/write from/to a memory region
that is in BE format per ASIC spec.
This patch has been tested in x86 and powerpc platform.
