Linux kernel source tree

Drivers that need to tweak a device IDENTIFY data implement the read_id() port operation. The IDENTIFY data buffer is passed as an argument to the read_id() operation for drivers to use. However, when this operation is called, the IDENTIFY data is not yet converted to CPU endian and contains le16 words. Change the interface of the read_id operation to pass a __le16 * pointer to the IDENTIFY data buffer to clarify the buffer endianness. Fix the pata_netcell, pata_it821x, ahci_xgene, ahci_ceva and ahci_brcm drivers implementation of this operation and modify the code to corretly deal with identify data words manipulation to avoid sparse warnings such as: drivers/ata/ahci_xgene.c:262:33: warning: invalid assignment: &= drivers/ata/ahci_xgene.c:262:33: left side has type unsigned short drivers/ata/ahci_xgene.c:262:33: right side has type restricted __le16 Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com> Reviewed-by: Hannes Reinecke <hare@suse.de> |

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.
