Instead of including c files with function definitions, you should add
function prototypes to header files (it seems you already did so) and
include only the header files. Include these header files in the c files
which call the functions as well as in the c files which define the
It is obviously necessary to modify the Makefile to have aic7?xx_osm_o.o
and aic7?xx_inline.o linked to an appropriate .ko file.
Furthermore, aic7?xx_inline.c are not very fitting file names since they
do not contain inline functions. aic7?xx_osm_o.c are somewhat strange
names either. Can't you move the functions into existing c files? E.g.
into those which contain most of the calls to the now de-inlined
functions. From the point of view of cross-OS driver maintenance (but
not necessarily from the point of view of Linux driver maintenance), it
may be useful to distinguish between functions used across OSs and those
used only in Linux when deciding where to move the functions.
