[PATCH 07/10] ARM: omap2: remove unused functions
From: Arnd Bergmann
Date: Mon Oct 24 2022 - 13:29:40 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
These are a number of individual functions that were either never
used, or that had their last user removed in a prior cleanup.
Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>
