ata: make qc_prep return ata_completion_errors

2019-11-01T14:50:51Z

In case a driver wants to return an error from qc_prep, return enum ata_completion_errors. sata_mv is one of those drivers -- see the next patch. Other drivers return the newly defined AC_ERR_OK. [v2] use enum ata_completion_errors and AC_ERR_OK. Signed-off-by: Jiri Slaby Cc: Jens Axboe Cc: linux-ide@vger.kernel.org Signed-off-by: Jens Axboe

treewide: Add SPDX license identifier for more missed files

2019-05-21T08:50:45Z

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 Signed-off-by: Greg Kroah-Hartman

ata: macio: Use of_node_name_eq for node name comparisons

2019-02-08T13:45:40Z

Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer. Cc: linux-ide@vger.kernel.org Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Rob Herring Signed-off-by: Jens Axboe

scsi: communicate max segment size to the DMA mapping code

2019-01-23T01:40:59Z

When a host driver sets a maximum segment size we should not only propagate that setting to the block layer, which can merge segments, but also to the DMA mapping layer which can merge segments as well.

ata: pata_macio: add of_node_put()

2018-12-21T14:12:25Z

of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. This place doesn't do that, so fix it. Acked-by: Bartlomiej Zolnierkiewicz Signed-off-by: Yangtao Li Signed-off-by: Jens Axboe

pata_macio: Delete an error message for a failed memory allocation in two functions

2018-02-18T13:24:16Z

Omit an extra message for a memory allocation failure in these functions. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Tejun Heo

ata: constify of_device_id structures

2017-03-06T20:18:01Z

Declare of_device_id structures as const as they are either passed to the macro MODULE_DEVICE_TABLE or stored in the of_match_table field of a device_driver structure. This field is of type const, so of_device_id structures having this property can be made const too. Cross compiled the files drivers/ata/pata_macio.c and drivers/ata/pata_mpc52xx.c for powerpc architecture. Signed-off-by: Bhumika Goyal Signed-off-by: Tejun Heo

PCI: Remove includes of asm/pci-bridge.h

2016-02-05T22:29:28Z

Drivers should include asm/pci-bridge.h only when they need the arch- specific things provided there. Outside of the arch/ directories, the only drivers that actually need things provided by asm/pci-bridge.h are the powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*. Remove the includes of asm/pci-bridge.h from the other drivers, adding an include of linux/pci.h if necessary. Signed-off-by: Bjorn Helgaas

ata: pata_macio: Fix module autoload for OF platform driver

2015-09-17T15:14:25Z

This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. This patch adds the missing MODULE_DEVICE_TABLE() for OF to export that information so modules have the correct aliases built-in and autoloading works correctly.

powerpc: Move Power Macintosh drivers to generic byteswappers

2015-03-23T03:29:40Z

ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.
