Subject: [PATCH 6/6] [v2] asm-generic: remove extra strn{cpy_from,len}_user declarations
Date: Sat, 15 May 2021 12:18:03 +0200	[thread overview]
Message-ID: <20210515101803.924427-7-arnd@kernel.org> (raw)
In-Reply-To: <20210515101803.924427-1-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.
