Linus Torvalds fe81ba137e ATA changes for 5.17-rc1
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
 details, 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

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
