Trying to use the master without this change results in the kernel boot process waiting forever for an interrupt that will never occur while attempting to probe any slave devices configured in the device tree as being under SPI master 1.

Thanks for sending the patch to the mainline list.
One little nitpick about the patchformat though:

Please add linebreaks after 70-75 characters for readability. And remove the
"Hello,\n\n" otherwise this would land in the final git commit, where it
doesn't belong.
For reference have a look at Documentation/SubmittingPatches in the kernel
tree.

Maybe Dinh can fix this up, otherwise he will tell you what to do.

Thanks,
Steffen
