Subject: [PATCH v2 07/20] powerpc/cell: Add __init attribute to eligible functions
Date: Thu, 16 Dec 2021 17:00:22 -0500	[thread overview]
Message-ID: <20211216220035.605465-8-nick.child@ibm.com> (raw)
In-Reply-To: <20211216220035.605465-1-nick.child@ibm.com>

Some functions defined in 'arch/powerpc/platforms/cell' are deserving of an
`__init` macro attribute. These functions are only called by other
initialization functions and therefore should inherit the attribute.
