Subject: [PATCH] arm64: errata: avoid duplicate field initializer
Date: Wed, 16 Mar 2022 19:37:45 +0100	[thread overview]
Message-ID: <20220316183800.1546731-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

The '.type' field is initialized both in place and in the macro
as reported by this W=1 warning:

arch/arm64/include/asm/cpufeature.h:281:9: error: initialized field overwritten [-Werror=override-init]

Remove the extranous initializer.

I see this warning on 5.17-rc8, but did not test it on linux-next,
which may already have a fix.
