Subject: [PATCH] scsi: hisi_sas: select CONFIG_RAS

The driver now uses the RAS infrastructure, and fails to link if that
is disabled:

drivers/scsi/hisi_sas/hisi_sas_v2_hw.o: In function `fatal_ecc_int_v2_hw':
hisi_sas_v2_hw.c:(.text+0xb08): undefined reference to `__tracepoint_non_standard_event'
drivers/scsi/hisi_sas/hisi_sas_v2_hw.o: In function `fatal_axi_int_v2_hw':
hisi_sas_v2_hw.c:(.text+0x1b34): undefined reference to `__tracepoint_non_standard_event'

This adds an explicit Kconfig 'select RAS' statement. I don't know if
the driver uses the interface correctly, as no other driver seems to do
it like this, but the change fixes the link error.

Fixes: dfeb5021f001 ("scsi: hisi_sas: report ECC and AXI errors in v2 hw to userspace")
