[PATCH 02/18] mpt3sas : Added mpt2sas driver definitions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



1. Added mpt2sas driver related macro's in mpt3sas header files
2. Made scsi host's, raid class's, pci's, ioctl's call back functions
as a gobal API's, so that both the drivers can use these
call back functions.
