Kernel for Galaxy S24, rebased on CLO sources (WIP)
cd94f74888
[ Upstream commit 44112922674b94a7d699dfff6307fc830018df7c ] Similar to how AHCI handles NCQ errors in ahci_error_intr() -> ata_port_abort() -> ata_do_link_abort(), add an NCQ error handler for LLDDs to call to initiate a link abort. This will mark all outstanding QCs as failed and kick-off EH. Note: A "force reset" argument is added for drivers which require the ATA error handling to always reset the device. A driver may require this feature for when SATA device per-SCSI cmnd resources are only released during reset for ATA EH. As such, we need an option to force reset to be done, regardless of what any EH autopsy decides. The SATA device FIS fields are set to indicate a device error from ata_eh_analyze_tf().

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.
