Merge tag 'ata-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata
Pull ATA updates from Damien Le Moal:
"A larger than usual set of changes for this cycle. The bulk of the
changes are part of a rework of libata messages and debugging features
from Hannes. In more detail, the changes are as follows.
- Small code cleanups in the pata_ali driver (unnecessary variable
initialization and simplified return statement, from Jason and
Colin.
- Switch to using struct_group() in the sata_fsl driver, from Kees.
- Convert many sysfs attribute show functions to use sysfs_emit()
instead of snprintf(), from me.
- sata_dwc_460ex driver code cleanups, from Andy.
- Improve DMA setup and remove superfluous error message in
libahci_platform, from Andy
- A small code cleanup in libata to use min() instead of open coding
test, from Changcheng.
- Rework of libata messages from Hannes. This is especially focused
on replacing compile time defined debugging messages (DPRINTK() and
VPRINTK()) with regular dynamic debugging messages (pr_debug()) and
traceipoint events. Both libata-core and many drivers are updated
to have a consistent debugging level control for all drivers.
- Extend compile test support to as many drivers as possible in ATA
Kconfig to improve compile test coverage, from me.
- Fixes to avoid compile time warnings (W=1) and sparse warnings in
sata_fsl and ahci_xgene drivers, from me.
- Fix the interface of the read_id() port operation method to clarify
that the data buffer passed as an argument is little endian. This
avoids sparse warnings in the pata_netcell, pata_it821x,
ahci_xgene, ahci_cevaxi and ahci_brcm drivers. From me.
- Small code cleanup in the pata_octeon_cf driver, from Minghao.
- Improved IRQ configuration code in pata_of_platform, from Lad.
- Simplified implementation of __ata_scsi_queuecmd(), from Wenchao.
- Debounce delay flag renaming, from Paul.
- Add support for AMD A85 FCH (Hudson D4) AHCI adapters, from Paul"
