Hi stable folks,

Please apply commit 5b1e38c0792c ("dpaa2-mac: bail if the dpmacs fwnode
is not found") to 5.15, where it addresses an instance of
-Wsometimes-uninitialized with clang-21 and newer, introduced by commit
3264f599c1a8 ("net: dpaa2-mac: Add ACPI support for DPAA2 MAC driver")
in 5.14.

  drivers/net/ethernet/freescale/dpaa2/dpaa2-mac.c:54:13: error: variable 'parent' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
     54 |         } else if (is_acpi_node(fwnode)) {
        |                    ^~~~~~~~~~~~~~~~~~~~
  drivers/net/ethernet/freescale/dpaa2/dpaa2-mac.c:58:29: note: uninitialized use occurs here
     58 |         fwnode_for_each_child_node(parent, child) {
        |                                    ^~~~~~
  drivers/net/ethernet/freescale/dpaa2/dpaa2-mac.c:54:9: note: remove the 'if' if its condition is always true
     54 |         } else if (is_acpi_node(fwnode)) {
        |                ^~~~~~~~~~~~~~~~~~~~~~~~~
  drivers/net/ethernet/freescale/dpaa2/dpaa2-mac.c:43:39: note: initialize the variable 'parent' to silence this warning
     43 |         struct fwnode_handle *fwnode, *parent, *child  = NULL;
        |                                              ^
        |                                               = NULL

It applies and builds cleanly for me. If there are any issues, please
let me know.

Cheers,
Nathan
