Subject: [PATCH v4 24/27] shed: fix kernel-doc markup
Date: Mon, 16 Nov 2020 11:18:20 +0100	[thread overview]
Message-ID: <7cf5d2691e70ab82c332a335d21f6f04c0f742ab.1605521731.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1605521731.git.mchehab+huawei@kernel.org>

Kernel-doc requires that a kernel-doc markup to be immediatly
below the function prototype, as otherwise it will rename it.
So, move sys_sched_yield() markup to the right place.

Also fix the cpu_util() markup: Kernel-doc markups
should use this format:
        identifier - description
