[PATCH v2 24/51] scsi: ips: don't return 0 from writes to the proc file

[Christian Brauner]

ips_write_info() ignores what is written to /proc/scsi/ips/<n> and
returns 0. Writers that use stdio, echo for example, take that as no
progress and retry forever. Return the number of bytes that were
written.
