X-Git-Tag: v2.6.13-rc1~90^2~583^2~62^2^2~27^2~45
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0d0c79747e362ff54adc6418d2990d49cad9395d;p=linux-2.6

[SCSI] mptfusion: mptscsih Split driver support

(1) mptscsih.c: Remove credits, -sralston references , update copyright
(2) mptscsih.c: split driver support
(3) mptscsih.c: module_init, module_exit, and probe routines moved to new
stub drivers, mptfc and mptspi
(4) mptscsih.c: some global parameters are moved to MPT_SCSI_HOST
(5) mptscsih.c: removed scsi_device_online check.

 /*
  *  linux/drivers/message/fusion/mptscsih.c
- *      High performance SCSI / Fibre Channel SCSI Host device driver.
- *      For use with PCI chip/adapter(s):
- *          LSIFC9xx/LSI409xx Fibre Channel
+ *      For use with LSI Logic PCI chip/adapter(s)
  *      running LSI Logic Fusion MPT (Message Passing Technology) firmware.
  *
- *  Credits:
- *      This driver would not exist if not for Alan Cox's development
- *      of the linux i2o driver.
- *
- *      A special thanks to Pamela Delaney (LSI Logic) for tons of work
- *      and countless enhancements while adding support for the 1030
- *      chip family.  Pam has been instrumental in the development of
- *      of the 2.xx.xx series fusion drivers, and her contributions are
- *      far too numerous to hope to list in one place.
- *
- *      A huge debt of gratitude is owed to David S. Miller (DaveM)
- *      for fixing much of the stupid and broken stuff in the early
- *      driver while porting to sparc64 platform.  THANK YOU!
