This patch is broken:

ERROR: modpost: "N_CSI_RX_FE_CTRL_DLANES" [drivers/staging/media/atomisp/atomisp.ko] undefined!
ERROR: modpost: "N_LONG_PACKET_LUT_ENTRIES" [drivers/staging/media/atomisp/atomisp.ko] undefined!
ERROR: modpost: "N_SHORT_PACKET_LUT_ENTRIES" [drivers/staging/media/atomisp/atomisp.ko] undefined!

Please test your patches before submitting them.

I suspect that the header declaring them weren't included at csi_rx.c.

Regards,
Mauro
