Subject: [PATCH v11 08/11] RISC-V: Export SBI error to linux error mapping function
Date:   Tue, 17 Mar 2020 18:11:41 -0700
Message-Id: <20200318011144.91532-9-atish.patra@wdc.com>
In-Reply-To: <20200318011144.91532-1-atish.patra@wdc.com>
References: <20200318011144.91532-1-atish.patra@wdc.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

All SBI related extensions will not be implemented in sbi.c to avoid
bloating. Thus, sbi_err_map_linux_errno() will be used in other files
implementing that specific extension.

Export the function so that it can be used later.
