A number of fixes:
  - bridge:
    - samsung-dsim: fix GPIO lifetime
  - client: Null pointer dereference fix
  - imagination: error handling fix, page handling fix
  - nouveau: fix reference leaks, double-frees, out-of-bounds accesses,
    use-after-frees, don't reject config without SCDC,  a number of
    workarounds
  - virtio: fix memory leak, reference leaks, null pointer dereference,
    add pixel blend mode, cache coherency fix

+menuconfig FWCTL
+	tristate "fwctl device firmware access framework"
+	help
+	  fwctl provides a userspace API for restricted access to communicate
+	  with on-device firmware. The communication channel is intended to
+	  support a wide range of lockdown compatible device behaviors including
+	  manipulating device FLASH, debugging, and other activities that don't
+	  fit neatly into an existing subsystem.
+
+if FWCTL
+
+config RUST_FWCTL_ABSTRACTIONS
+	bool "Rust fwctl abstractions"
+	depends on RUST && FWCTL=y
+	help
+	  This enables the Rust abstractions for the fwctl device firmware
+	  access framework. It provides safe wrappers around struct fwctl_device
+	  and struct fwctl_uctx, allowing Rust drivers to register fwctl devices
+	  and implement their control and RPC logic in safe Rust.
+
+	  If unsure, say N.
+
+config FWCTL_BNXT
+	tristate "bnxt control fwctl driver"
+	depends on BNXT
+	help
+	  BNXT provides interface for the user process to access the debug and
+	  configuration registers of the Broadcom NIC hardware family.
+	  This will allow configuration and debug tools to work out of the box on
+	  mainstream kernel.
+
+	  If you don't know what to do here, say N.
+
+config FWCTL_MLX5
+	tristate "mlx5 ConnectX control fwctl driver"
+	depends on MLX5_CORE
+	help
+	  MLX5 provides interface for the user process to access the debug and
+	  configuration registers of the ConnectX hardware family
+	  (NICs, PCI switches and SmartNIC SoCs).
+	  This will allow configuration and debug tools to work out of the box on
+	  mainstream kernel.
+
+	  If you don't know what to do here, say N.
+
+config FWCTL_PDS
+	tristate "AMD/Pensando pds fwctl driver"
+	depends on PDS_CORE
+	help
+	  The pds_fwctl driver provides an fwctl interface for a user process
+	  to access the debug and configuration information of the AMD/Pensando
+	  DSC hardware family.
+
+	  If you don't know what to do here, say N.
