Subject: [PATCH v3 31/32] spi: Drop compat layer from renaming "master" to "controller"
Date: Wed,  7 Feb 2024 19:40:45 +0100
Message-ID:  <ad1d949325b61a4682e8d6ecf9d05da751e6a99f.1707324794.git.u.kleine-koenig@pengutronix.de>

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"")
