Subject: [PATCH 5.18 151/231] ARM: 9211/1: domain: drop modify_domain()

From: Linus Walleij <linus.walleij@...aro.org>

[ Upstream commit cc45b836388f0ccc6831288a08f77a33845f10b0 ]

This function/macro isn't used anywhere in the kernel.
The only user was set_fs() and was deleted in the set_fs()
removal patch set.

Fixes: 8ac6f5d7f84b ("ARM: 9113/1: uaccess: remove set_fs() implementation")
Acked-by: Arnd Bergmann <arnd@...db.de>
