A fix that addresses incorrect release of Rx buffer ownership in the driver. The fix specificially avoids releasing Rx buffer ownership with FFA_RX_RELEASE if it wasn’t acquired during a FFA_PARTITION_INFO_GET call that only requested the partition count. This prevents unnecessary errors like FFA_RET_DENIED from firmware when buffers are not actually owned by the driver. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmf3xDIACgkQAEG6vDF+ 4ph+YRAAu+EXYDSopYHSjmFQ+pY7KUncSE4sG2MPJL06jPO6ldaQ71amQkxm7bW3 KyqXaMBX1mlyHH6RSIY1/cIM3D0a3ubfbS6pjVpz9z5ZteNyYob5MGtE7eho6Swa pVa/OuNEfF6lXKb8O1eY1xHWGTs/573bVnvqfqKtZnIjNiYAo+pHJzEv+m53U9oF l0HoaSC6BNgPnVtFdd0z6fCOcCjw9DCluo5j9cvdMGsG6pG+F3mn4iT+7P6uvcFl XFhuO15+uItbRbZ1QZynZklCa1u99wMCo/+N0FpZiStqC22X6IpAs8FiaqaGpiBY 27znwncqyW3U2lwl0ZYWdMKjlvzUoaZroM7pwu9Kcjtlvb4gF0MzJWSfWTRAMSbK tAeqQb5zvkiogoDLp3HfQTf+xpqvU6Qn90jpzkawhmyFgcAzR3xHuHX1t2VHY6ye SfydmOvcz48sS+BxHl3/T2p6zGximT3oZ8gO9uSe0IvRgw2ZJE1RZzoSCJrZTDF0 +ktjDJtMembjSzuNpmOXdGjk2PCWQT/7bmjKe1tg2v2qvD+MEXMiryahQoeovgME FJR9VvOlL4JVN3ouE5wppqey6ViZmt+bu6Pg3Y6/oNQNt9gJvB7yqODGPHwfEo8r Z4y9EoDr6qy7r03ihLEa84KMh/LBBCj3dF4SJRWxT/GVJm5K2q4= =e5sa -----END PGP SIGNATURE----- Merge tag 'ffa-fix-6.15' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm FF-A fix for v6.15 A fix that addresses incorrect release of Rx buffer ownership in the driver.

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.
