Subject: [PATCH] staging: comedi: comedidev.h: remove 'new_size' param from
 subdevice (*buf_change)

This parameter is never used by any of the comedi drivers that provide a
(*buf_change) callback. If the 'new_size' is needed in the callback it can
be found from the 's->async->prealloc_bufsz' as done in the ni_pcidio driver.

Remove the unused parameter.
