From: Bo Gan Date: Tue, 5 Mar 2024 18:35:36 -0800 Subject: [PATCH v4 3/7] lib: sbi: change prototype of sbi_trap_redirect In-Reply-To: <1709692540-77803-1-git-send-email-ganboing@gmail.com> References: <1709692540-77803-1-git-send-email-ganboing@gmail.com> Message-ID: <1709692540-77803-4-git-send-email-ganboing@gmail.com> List-Id: To: opensbi@lists.infradead.org MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit sbi_trap_redirect now uses const pointer to `trap`. This ensures the caller that we never change `trap` in sbi_trap_redirect.
