ata: sata_dwc_460ex: Convert to platform remove callback returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

ata: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

ata: sata_dwc_460ex: Check !irq instead of irq == NO_IRQ NO_IRQ is a relic from the old days. It is not used anymore in core functions. By the way, function irq_of_parse_and_map() returns value 0 on error. In some drivers, NO_IRQ is erroneously used to check the return of irq_of_parse_and_map(). It is not a real bug today because the only architectures using the drivers being fixed by this patch define NO_IRQ as 0, but there are architectures which define NO_IRQ as -1. If one day those architectures start using the non fixed drivers, there will be a problem. Long time ago Linus advocated for not using NO_IRQ, see https://lkml.org/lkml/2005/11/21/221 . He re-iterated the same view recently in https://lkml.org/lkml/2022/10/12/622 So test !irq instead of tesing irq == NO_IRQ. And remove the fallback definition of NO_IRQ at the top of the file.

Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32, the value of the SATA_DWC_QCMD_MAX needs to account for that.

With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1. This avoids the OOB. But please note, there was a worthwhile discussion on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not be a "fake" 33 command-long queue size. Ideally, the dw driver should account for the ATA_TAG_INTERNAL. In Damien Le Moal's words: "... having looked at the driver, it is a bigger change than just faking a 33rd "tag" that is in fact not a command tag at all."

However, those names are not defined as macros on ppc, so it ended up replacing them there as well with altered semantics. This patch restores the original semantics on ppc and makes the accesses no less strict on other systems. Also fixes too many sparse warnings to count.

ata: sata_dwc_460ex: burst size must be in items not bytes The burst size as defined by DMAengine API is in items of address width. Derive burst size from AHB_DMA_BRST_DFLT (64 bytes) by dividing it to DMA_SLAVE_BUSWIDTH_4_BYTES (4 bytes) that gives us 16 items.

ata: sata_dwc_460ex: set dma_boundary to 0x1fff The original code states: Make sure a LLI block is not created that will span 8K max FIS boundary. If the block spans such a FIS boundary, there is a chance that a DMA burst will cross that boundary -- this results in an error in the host controller. Since we have switched to generic DMAengine API we satisfy above by setting dma_boundary value to 0x1fff.

dmaengine: dw: rename masters to reflect actual topology The source and destination masters are reflecting buses or their layers to where the different devices can be connected. The patch changes the master names to reflect which one is related to which independently on the transfer direction. The outcome of the change is that the memory data width is now always limited by a data width of the master which is dedicated to communicate to memory. The patch will not break anything since all current users have the same data width for all masters. Though it would be nice to revisit avr32 platforms to check what is the actual hardware topology in use there. It seems that it has one bus and two masters on it as stated by Table 8-2, that's why everything works independently on the master in use. The purpose of the sequential patch is to fix the driver for configuration of more than one bus. The change is done in the assumption that src_master and dst_master are reflecting a connection to the memory and peripheral correspondently on avr32 and otherwise on the rest.

drivers/ata/sata_dwc_460ex.c: add missing kfree Currently, error handling code in this function calls the function sata_dwc_port_stop, but this function has essentially no effect if hsdevp has not been stored in ap, which is the case throughout this function. The only effect is to print a debugging message including ap->print_id. The code is rewritten to not call sata_dwc_port_stop, but instead to jump to a local label that prints the original error message and the print_id information. In the case where hsdevp has been already allocated (but not yet stored in ap), this value is freed as well. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression x; statement S,S1; expression E; identifier fl; expression *ptr != NULL; @@ x = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...kfree(x)...+> } when any when != true x == NULL x->fl ...> ( if (x == NULL) S1 | if (...) { ... when != x when forall ( return \(0\|<+...x...+>\|ptr\); | * return ...; ) } ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
