Subject: [PATCH v3 8/9] asm-generic: remove extra strn{cpy_from,len}_user declarations
Date:   Thu, 22 Jul 2021 14:48:13 +0200
Message-Id: <20210722124814.778059-9-arnd@kernel.org>
In-Reply-To: <20210722124814.778059-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

As these are now in asm-generic, it's no longer necessary to
declare them in the architecture.
