New Revision: 304069
URL: https://svnweb.freebsd.org/changeset/base/304069
Log:
Return 0 instead of an error code on failure to find dcsr.
mpc85xx_map_dcsr() returns a vm_offset_t, not an error code.
mpc85xx_fix_errata() will gracefully exit if mpc85xx_map_dcsr() returns 0, as
that indicates an error (NULL pointer).
