Hi Linus,

Due to the linux-next break until January 4, not all of them have been in
linux-next; no conflicts expected.

fs/kernfs: null-ptr deref in simple_xattrs_free() (2025-12-23 16:14:43 +0100)

----------------------------------------------------------------
Driver core fixes for 6.19-rc3

- Introduce DMA Rust helpers to avoid build errors when !CONFIG_HAS_DMA.

- Remove unnecessary (and hence incorrect) endian conversion in the Rust
PCI driver sample code.

- Fix memory leak in the unwind path of debugfs_change_name().

- Support non-const struct software_node pointers in
SOFTWARE_NODE_REFERENCE(), after introducing _Generic().

- Avoid NULL pointer dereference in the unwind path of
simple_xattrs_free().
