Subject: [PATCH v10 08/12] RISC-V: Export SBI error to linux error mapping function
Date: Wed, 26 Feb 2020 14:02:09 -0800 [thread overview]
Message-ID: <20200226220213.27423-9-atish.patra@wdc.com> (raw)
In-Reply-To: <20200226220213.27423-1-atish.patra@wdc.com>
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.
