A bunch of fixes addressing issues around the notification support that was added this cycle. They address issue in partition IDs handling in ffa_notification_info_get(), notifications cleanup path and the size of the allocation in ffa_partitions_cleanup(). It also adds check for the notification enabled state so that the drivers registering the callbacks can be rejected if not enabled/supported. It also moves the partitions setup operation after the notification initialisation so that the driver has the correct state for notification enabled/supported before the partitions are initialised/setup. It also now allows FF-A initialisation to complete successfully even when the notification initialisation fails as it is an optional support in the specification. Initial support just allowed it only if the firmware didn't support notifications. Finally, it also adds a fix for smatch warning by declaring ffa_bus_type structure in the header. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmVWagYACgkQAEG6vDF+ 4pjtzg//blfExUD8Eu78LtL0CL58qzUrA1bOwT52xbGl202hoykgB49x0YJ4uZMP edkwPeUzT1sizvd2/kI+q7qjCrBqwwmaFGD1QUzMX0O7d9bpNZ2r8xzrTEDTUvOh yLi4F6D1m50lY2ZFq/8iu/eTtrAHKX0zzmnz0NgNLqITbOMpp1GAvUkhFJjmL4c+ 8MPZL3hHOfVV4m06YQHmpHEbdZiJ5iqY38nXW4Lyl9xQOO9E7/OU48bt5+fFC1SN E3PRGrqFKz4O2iCOCEb/mIa94fOjaO4ymgc1/jtUUSZ3ok4+yQlz2ZK2JNPQbwhs C8MB/arxIWBdNKejXjUquPiZ4z3FbFIG9A3MptxFQQH6QudygldxifVcqh6AUeJa 44iaz0Il7oFZF1E1iiMqKHdQEoKXLo0IiGJlBkwTrUKqEQQ0V12hLcujVxKcHMxh /UTE5R/yzo5It9NiS9RSHzavTXSbe6B66zepSJv0sm3YWwgaaJZ1uShKHhs9L99L rPfTXHcAk5QTCWn66KLnNAW7NzdZ/2paZ+G7gNadqRcVyYdk9Vce3C4HXmse7eOk 6nfOaRrOSCKFbH5q05k7JUcV6On+2fUFHFpQOnxxatglrpf08WHVLsir5s8DyiZ3 WC81z23HkoqnNZ63ofw5FUdervQSmB3iK+m+R7Hqrowqg9lcT1U= =mgRO -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmVwotEACgkQYKtH/8kJ Uif3QA/+MGZdnJywBQKQ89cFl1LMBYhm6+NC/qr6zzTJX8hwAuO31yR4WzUb6H2M Y+kZKXmWUYz98ylSBDLXWAWjfI1bHr68h+4LHPWway9SPfrt9ZtTdI0m3kTtcuTQ mIa8mkewa2MnD6lxjmkl5jUHjywpFsSCJGHnCRYmoCkUtGVDbXqp4ByBhpQPIBGu FeTj8w4EQ3MIf7zIMqm6UmpRrB+zUjwPeinHBcsv6DJvTSn2dWyqpJ1DhoA6Ulkk xBrULU2pE6b1qP6WwG81+Nsrdg9NIaO29PNBylEyQQEYQGPTvRwcfVouhRKmeAUk 2C1JOujbLk67CRfvD5CCyxvptJPW++3scrFFFY1R56B8Z+xz2Kx/IlkXv7U4W5xy AWU7kYzWY4andQdzoM1S8M+qwgWKcQ9QiddHOHgnqLLvgn8HOAYUF2LdJneHdr+t MZpKKAfYyBlz0tXT7p6YoHDVIRe5pQgb5Pd+irFCpk/40b+xoV4OD4u+zO7JW2e8 DUGvIbNwQsT8lpgQLmYJfoLZJzEVpHXUiQ9h5g8gzVnL4cDKsvxlvWc6RFTZxDaD FgHHQhY0qPyEzVNrw/88QnaT/3XwgB2Boyx1BbYmNovfHRX2zw/UsEQlVNwCjzZ9 mSUNXTCjfA1sYeX5Akah2upswstNEfs8xWMTLLywsxtJ6SB1zPI= =4Rj2 -----END PGP SIGNATURE----- Merge tag 'ffa-fixes-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm FF-A fixes for v6.7 A bunch of fixes addressing issues around the notification support that was added this cycle.

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.
