devm_spi_alloc_master() was introduced in v5.10-rc5 with commit
5e844cc37a5c and then backported to 5.9-stable and 5.4-stable.

Patches are pending to also backport it to 4.19-stable, 4.14-stable,
4.9-stable and 4.4-stable.

If your development branch is based on v5.5, just cherry-pick
5e844cc37a5c and you should be good to go.

Thanks,

Lukas
