I see devm_spi_alloc_master() in 5.4 but not from 5.5 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
