+Subject: drivers: base: handle module_kobject creation
+
+From: Shyam Saini <shyamsaini@linux.microsoft.com>
+
+[ Upstream commit f95bbfe18512c5c018720468959edac056a17196 ]
+
+module_add_driver() relies on module_kset list for
+/sys/module/<built-in-module>/drivers directory creation.
+
+Since,
+commit 96a1a2412acba ("kernel/params.c: defer most of param_sysfs_init() to late_initcall time")
+drivers which are initialized from subsys_initcall() or any other
+higher precedence initcall couldn't find the related kobject entry
+in the module_kset list because module_kset is not fully populated
+by the time module_add_driver() refers it. As a consequence,
+module_add_driver() returns early without calling make_driver_name().
+Therefore, /sys/module/<built-in-module>/drivers is never created.
+
+Fix this issue by letting module_add_driver() handle module_kobject
+creation itself.
+
+Fixes: 96a1a2412acb ("kernel/params.c: defer most of param_sysfs_init() to late_initcall time")

+Subject: drm/amd/display: Fix slab-use-after-free in hdcp
+
+From: Chris Bainbridge <chris.bainbridge@gmail.com>
+
+[ Upstream commit be593d9d91c5a3a363d456b9aceb71029aeb3f1d ]
+
+The HDCP code in amdgpu_dm_hdcp.c copies pointers to amdgpu_dm_connector
+objects without incrementing the kref reference counts. When using a
+USB-C dock, and the dock is unplugged, the corresponding
+amdgpu_dm_connector objects are freed, creating dangling pointers in the
+HDCP code. When the dock is plugged back, the dangling pointers are
+dereferenced, resulting in a slab-use-after-free:

+MIME-Version: 1.0

+[ Upstream commit 4567bdaaaaa1744da3d7da07d9aca2f941f5b4e5 ]
+
+Completion of the FFA_PARTITION_INFO_GET ABI transfers the ownership of
+the caller’s Rx buffer from the producer(typically partition mnager) to
+the consumer(this driver/OS). FFA_RX_RELEASE transfers the ownership
+from the consumer back to the producer.
+
+However, when we set the flag to just return the count of partitions
+deployed in the system corresponding to the specified UUID while
+invoking FFA_PARTITION_INFO_GET, the Rx buffer ownership shouldn't be
+transferred to this driver. We must be able to skip transferring back
+the ownership to the partition manager when we request just to get the
+count of the partitions as the buffers are not acquired in this case.
+
+Firmware may return FFA_RET_DENIED or other error for the ffa_rx_release()
+in such cases.

+Subject: firmware: arm_scmi: Balance device refcount when destroying devices
+
+From: Cristian Marussi <cristian.marussi@arm.com>
+
+[ Upstream commit 9ca67840c0ddf3f39407339624cef824a4f27599 ]
+
+Using device_find_child() to lookup the proper SCMI device to destroy
+causes an unbalance in device refcount, since device_find_child() calls an
+implicit get_device(): this, in turns, inhibits the call of the provided
+release methods upon devices destruction.
+
+As a consequence, one of the structures that is not freed properly upon
+destruction is the internal struct device_private dev->p populated by the
+drivers subsystem core.
+
+KMemleak detects this situation since loading/unloding some SCMI driver
+causes related devices to be created/destroyed without calling any
+device_release method.

+This commit renames locate_module_kobject() to

+This reverts commit bfbc68e.
+
+The patch does permit the offending YUV420 @ 59.94 phy_freq and
+vclk_freq mode to match in calculations. It also results in all
+fractional rates being unavailable for use. This was unintended
