Subject: [PATCH v2 04/29] tcg: Remove error return from tcg_region_initial_alloc__locked
Date: Sun, 14 Mar 2021 15:26:59 -0600 [thread overview]
Message-ID: <20210314212724.1917075-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210314212724.1917075-1-richard.henderson@linaro.org>
All callers immediately assert on error, so move the assert
into the function itself.
