Hi Sreekanth,
In
[PATCH 11/20] [SCSI] mpt3sas: Add branding string support for OEM custom HBA
you add _base_display_cisco_branding(). In
[PATCH 10/20] [SCSI] mpt3sas: Add branding string support for OEM's HBA
you add _base_display_dell_branding(). You already have
_base_display_intel_branding().
Each of them follows the pattern:
1) Check if it is a OEM device for XXX
2) Check witch OEM device for XXX it is
3) Display a string based on that specific OEM device
4) Return
