Similarly to 'buf' in the previous patch, there is no need to have a
separate counter ('remaining') in srmcons_do_write(). 'count' can be
used directly which simplifies the code a bit.
Note that the type of the current count ('c') is changed from 'long' to
'size_t' so that:
1) it is prepared for the upcoming change of 'count's type, and
2) is unsigned.

The patches in the series are in pretty odd order and it was not told
anywhere here that the return value is unused by the callers. I'd just
reorder the patches.
Agreed, patch 15 needs to be before patch 14. With that,
