Please don't put spaces after '(' and before ')'.

And this trick isn't really needed.  If you do

        if (whatever = constant)

then the compiler will generate a warning.  Please do these comparisons in
the conventional way, with the constant on the right hand side.

Lots more extraneous spaces after '(' and before ')'.

No braces here.

And here.

and here...

We do put a space after `if', so this line should be

        if (bus) {

> +struct spi_bus* spi_bus_find( char* id )

The asterisk goes with the variable, not with the type.  So the above should be

        struct spi_bus *spi_bus_find(char *id)

> +int spi_device_add( struct spi_bus* bus, struct spi_device *dev, char* name)

Here too.

You seem to have an awful lot of non-static functions.  Please check
whether they all really need to have global scope.

        if (dev == NULL) {

Don't typecast void* when assigning to and from pointers.  It adds clutter
and defeats typechecking.

Ditto.

Labels go in column zero.

The above names are risky.  Some platform may implement copy_to_user() as a
macro.
