scsi: remove the sym53c416 driver
This driver hasn't seen any recent bug fixing and is one of the last drivers using the scsi_module.c infrastruture that has been deprecated 15 years ago. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

This is support for the sym53c416 SCSI host adapter, the SCSI
|
||||
adapter that comes with some HP scanners. This driver requires that
|
||||
the sym53c416 is configured first using some sort of PnP
|
||||
configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
|
||||
are using isapnp then you need to compile this driver as a module
|
||||
and then load it using insmod after isapnp has run. The parameters
|
||||
of the configured card(s) should be passed to the driver. The format
|
||||
is:
|
||||
|
||||
insmod sym53c416 sym53c416=<base>,<irq> [sym53c416_1=<base>,<irq>]
|
||||
|
||||
To compile this driver as a module, choose M here: the
|
||||
module will be called sym53c416.
