Subject: Merge tag 'drm-misc-fixes-2026-09-24' of
 https://gitlab.freedesktop.org/drm/misc/kernel into drm-fixes

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

+  The Util Sigma-Delta SPI is an FPGA IP core from Analog Devices that provides
+  a SPI offload trigger from the RDY signal of the combined DOUT/RDY pin of
+  the sigma-delta family of ADCs.
