commit
5e5ec1759dd663a1d5a2f10930224dd009e500e8 upstream.
This patch will fix regression caused by commit
1e793f6fc0db ("scsi:
megaraid_sas: Fix data integrity failure for JBOD (passthrough)
devices").
The problem was that the MEGASAS_IS_LOGICAL macro did not have braces
and as a result the driver ended up exposing a lot of non-existing SCSI
devices (all SCSI commands to channels 1,2,3 were returned as
SUCCESS-DID_OK by driver).
[mkp: clarified patch description]
