The previous code returned '\n' (that is, a single empty line)
from most files, with one exception (xmit_hash_policy), where
it returned 'NA\n'. This patch consolidates each file to return
nothing at all if not applicable, not even a '\n'.
I find this behaviour more usual, more useful, more efficient
and shorter to code from both sides.

Rather than this (returning nothing if not in xor or 802.3ad
mode), I'd prefer to see this always return whatever the xmit policy is
(regardless of the mode), and remove the mode test from
bonding_store_xmit_hash().
This would be consistent with the way the arp_ip_target option
is treated: the actual value is always displayed, even if it is not
used, and it is legal to change the value, regardless of the mode.
Other than this, I'm fine with the changes.

Also remove trailing spaces from multivalued files.
This fixes output like for example:
$ od -c /sys/class/net/bond0/bonding/slaves
0000000 e t h - l e f t e t h - r i g
0000020 h t \n \0
0000025
It mostly entails deleting '+1'-s after sprintf() calls: the return value
of sprintf is the number of characters printed, without the closing NUL,
ie. exactly what the sysfs interface requires. The three multivalue
cases are different, because they also have to swallow back a trailing
space.

Okay, I'm resending the full patch series with correct subject
counters accounting for the two followup patches taking care for your
comments (4 and 5). Please let me know if something is still missing.
Thanks,
