Introduce the function ata_dev_print_quirks() to print the quirk flags that will be applied to a scanned device. This new function is called from ata_dev_quirks() when a match on a device model or device model and revision is found for a device in the __ata_dev_quirks array. To implement this function, the ATA_QUIRK_ flags are redefined using the new enum ata_quirk which defines the bit shift for each quirk flag. The array of strings ata_quirk_names is used to define the name of each flag, which are printed by ata_dev_print_quirks(). Example output for a device listed in the __ata_dev_quirks array and which has the ATA_QUIRK_DISABLE flag applied: [10193.461270] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300) [10193.469190] ata1.00: Model 'ASMT109x- Config', rev '2143 5', applying quirks: disable [10193.469195] ata1.00: unsupported device, disabling [10193.481564] ata1.00: disable device enum ata_quirk also defines the __ATA_QUIRK_MAX value as one plus the last quirk flag defined. This value is used in ata_dev_quirks() to add a build time check that all quirk flags fit within the unsigned int (32-bits) quirks field of struct ata_device.

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 reStructuredText 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.
