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

From: Uwe Kleine-König
Date: Mon Jan 22 2024 - 14:18:34 EST


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"")
