[PATCH v2 32/33] spi: Drop compat layer from renaming "master" to "controller"

Uwe Kleine-König
2024-01-22T18:08:36Z

Now that all in-tree users followed the rename, the compat stuff can go
away. This completes the renaming started with commit 8caab75fd2c2
("spi: Generalize SPI "master" to "controller"")
