From 2f0b9d082e5d0056a3aca4be038483a564849196 Mon Sep 17 00:00:00 2001

Subject: [PATCH] staging: comedi: export alloc_subdevices as
 comedi_alloc_subdevices

Move the inline alloc_subdevices() function from comedidev.h
to drivers.c and rename it to comedi_alloc_subdevices(). The
function is large enough to warrant being an exported symbol
rather than being an inline in every driver.
