Hello, Drop this patch. Because sgpio_regs is optional which is used like this if (!hisi_hba->sgpio_regs) return -EOPNOTSUPP; > -----Original Message----- > From: Cai,Huoqing <caihuoqing@baidu.com> > Sent: 2021年9月1日 16:52 > To: Cai,Huoqing > Cc: John Garry; James E.J.

Use the devm_platform_ioremap_resource() helper instead of calling platform_get_resource() and devm_ioremap_resource() separately Signed-off-by: Cai Huoqing <caihuoqing@baidu.com> --- drivers/scsi/hisi_sas/hisi_sas_main.c | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-)
