RISC-V: Export SBI error to linux error mapping function (f90b43ce) · Commits · 戴 / test

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. Signed-off-by:
