commit a313bdc5310dd807655d3ca3eb2219cd65dfe45a upstream.

Fix this error when compiling with CONFIG_SMP=n and
CONFIG_DYNAMIC_DEBUG=y:

drivers/s390/char/sclp_early.c: In function 'sclp_read_info_early':
drivers/s390/char/sclp_early.c:87:19: error: 'EBUSY' undeclared (first use in this function)
} while (rc == -EBUSY);
^
