Subject: [PULL 04/34] tcg: Remove error return from tcg_region_initial_alloc__locked
Date: Fri, 11 Jun 2021 16:41:14 -0700	[thread overview]
Message-ID: <20210611234144.653682-5-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210611234144.653682-1-richard.henderson@linaro.org>

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