2019-05-21treewide: Add SPDX license identifier for more missed filesThomas Gleixner1-0/+1
Add SPDX license identifiers to all files which: - Have no license information of any form - Have MODULE_LICENCE("GPL*") inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-12-19scsi: flip the default on use_clusteringChristoph Hellwig1-1/+0
Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.

2018-11-15scsi: wd719x: always use generic DMA APIChristoph Hellwig1-15/+17
The wd719x driver currently uses a mix of the legacy PCI DMA and the generic DMA APIs. Switch it over to the generic DMA API entirely. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
2018-11-15scsi: wd719x: use per-command private dataChristoph Hellwig1-56/+42
Add the SCB onto the scsi command allocation and use dma streaming mappings for it only when in use. This avoid possibly calling dma_alloc_coherent under a lock or even in irq context, while also making the code simpler. Thanks to Ondrej Zary for testing and various bug fixes.

2018-11-15scsi: wd719x: there should be no active SCBs on removalChristoph Hellwig1-3/+2
Warn on that case instead of trying to free them which would be fatal in case we actually had active ones. [mkp: typos] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

2017-12-05scsi: wd719x: make card_types static const, shrinks object sizeColin Ian King1-1/+3
Don't populate the read-only array card_types on the stack but instead make it static and constify it. Makes the object code smaller by over 110 bytes: Before: text data bss dec hex filename 25625 5752 0 31377 7a91 drivers/scsi/wd719x.o After: text data bss dec hex filename 25447 5816 0 31263 7a1f drivers/scsi/wd719x.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Martin K.

Convert it to the preferred const struct pci_device_id instead.

2015-06-01scsi: Do not set cmd_per_lun to 1 in the host templateHannes Reinecke1-1/+0
'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 <hare@suse.de> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>
2015-02-15wd719x: add missing .module to wd719x_templateOndrej Zary1-0/+1
wd719x_template is missing the .module field, causing module refcount not to work, allowing to rmmod the driver while in use (mounted filesystem), causing an oops. Set .module to THIS_MODULE to fix the problem. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
