Subject: [PATCH v3 04/28] tcg: Remove error return from tcg_region_initial_alloc__locked
Date: Sun,  2 May 2021 16:18:20 -0700	[thread overview]
Message-ID: <20210502231844.1977630-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210502231844.1977630-1-richard.henderson@linaro.org>

All callers immediately assert on error, so move the assert
into the function itself.
