scsi: cciss: Drop obsolete driver

2017-08-25T02:28:57+00:00

The hpsa driver now has support for all boards the cciss driver used to support, so this patch removes the cciss driver and make hpsa an alias to cciss. Signed-off-by: Hannes Reinecke Acked-by: Don Brace Signed-off-by: Martin K. Petersen

cciss: Remove kmalloc cast

2017-02-22T18:54:49+00:00

Coccinelle emits a warning about casting the return value of kmalloc(). Coccinelle suggests removing the cast as do kerneljanitors. Remove cast from kmalloc() call. Signed-off-by: Tobin C. Harding Acked-by: Don Brace Signed-off-by: Jens Axboe

cciss: Fix checkpatch OPEN_BRACE

2017-02-22T18:54:49+00:00

Checkpatch emits ERROR:OPEN_BRACE: that open brace { should be on the previous line. Move open brace to new line. Also add space after if/switch statement since we introduce more checkpatch errors if not fixed at the same time. Signed-off-by: Tobin C. Harding Acked-by: Don Brace Signed-off-by: Jens Axboe

cciss: Fix checkpatch TRAILING_WHITESPACE

2017-02-22T18:54:49+00:00

Checkpatch emits 85 trailing whitespace warnings. Remove trailing whitespace. Signed-off-by: Tobin C. Harding Acked-by: Don Brace Signed-off-by: Jens Axboe

scsi: cciss: replace custom function to hexdump

2016-11-08T22:29:57+00:00

For small buffers we may use %*ph[N] specifier, for the bigger blocks print_hex_dump() call. Cc: Don Brace Cc: esc.storagedev@microsemi.com Signed-off-by: Andy Shevchenko Acked-by: Don Brace Signed-off-by: Martin K. Petersen

scsi: Do not set cmd_per_lun to 1 in the host template

2015-06-01T01:06:28+00:00

'0' is now used as the default cmd_per_lun value, so there's no need to explicitly set it to '1' in the host template. Signed-off-by: Hannes Reinecke Reviewed-by: Christoph Hellwig Signed-off-by: James Bottomley

cciss: switch to ->show_info()

cciss: fix handling of protocol error

2012-09-18T09:57:08+00:00

If a command completes with a status of CMD_PROTOCOL_ERR, this information should be conveyed to the SCSI mid layer, not dropped on the floor. Unlike a similar bug in the hpsa driver, this bug only affects tape drives and CD and DVD ROM drives in the cciss driver, and to induce it, you have to disconnect (or damage) a cable, so it is not a very likely scenario (which would explain why the bug has gone undetected for the last 10 years.)

cciss: fix incorrect scsi status reporting

2012-08-21T23:45:02+00:00

Delete code which sets SCSI status incorrectly as it's already been set correctly above this incorrect code. The bug was introduced in 2009 by commit b0e15f6db111 ("cciss: fix typo that causes scsi status to be lost.") Signed-off-by: Stephen M.

cciss: Fix scsi tape io with more than 255 scatter gather elements

2012-03-22T20:40:09+00:00

The total number of scatter gather elements in the CISS command used by the scsi tape code was being cast to a u8, which can hold at most 255 scatter gather elements. It should have been cast to a u16. Without this patch the command gets rejected by the controller since the total scatter gather count did not add up to the right value resulting in an i/o error.
