[PATCH] s390: fix sclp memory corruption in tty pages list
When the sclp interface takes very long to serve a request, the sclp core
driver will report a failed request to the sclp tty driver even though the
request is still being processed by the sclp interface. Eventually the sclp
interface completes the request and updates some fields in the request buffer
which leads to a corrupted tty pages list. The next time function
sclp_tty_write_room is called, the corrupted list will be traversed, resulting
in an oops.
To avoid this remove the busy retry limit and increase retry intervals.
