Clang is not on board:

drivers/ptp/ptp_ocp.c:384:32: warning: tentative definition of variable with internal linkage has incomplete non-array type 'const struct ocp_sma_op' [-Wtentative-definition-incomplete-type]
static const struct ocp_sma_op ocp_art_sma_op;
                               ^
drivers/ptp/ptp_ocp.c:349:15: note: forward declaration of 'struct ocp_sma_op'
        const struct ocp_sma_op *sma_op;
                     ^

You may need to throw an extern in there.

Is it not possible to just order things correctly in the first place? 
Is there a dependency cycle?
