[PATCH] sym53c500_cs PCMCIA SCSI driver (round 5)
Fifth attempt at a PCMCIA SCSI driver for the Symbios 53c500
controller. This version has all the cleanup Christoph has requested
to date, including removal of support for the obsolete (in 2.6)
proc_info functionality.
Support for additional sysfs class device attributes has been added:
two are read-only (irq, ioport), one is read-write (fast_pio). The
read-write attribute is a per-instance flag indicating the PIO speed
of the particular HBA: valid values are 1 (enabled -- default) and 0
(disabled).
