Hi all, I downloaded the QNAP kernel for x51 device -> 3.12.6, I fetch the config.gz from /proc and run make! But I get this error:

CC init/version.o
LD init/built-in.o
drivers/built-in.o: In function `usb_hc_died':

drivers/built-in.o: In function `fix_sync_read_error':

drivers/built-in.o:raid1.c:(.text+0x14eba8): more undefined references to `send_message_to_app' follow
make: *** [vmlinux] Error 1

It is an error on this function 'send_message_to_app'!!

Using grep I founded that function in drivers/qnap/:

drivers/qnap/pic.c:int send_message_to_app(unsigned short message)
drivers/qnap/pic.c:EXPORT_SYMBOL(send_message_to_app);
drivers/qnap/pic.c:int send_message_to_app_qraid1(unsigned char message)
drivers/qnap/pic.c:EXPORT_SYMBOL(send_message_to_app_qraid1);
drivers/qnap/pic-arm.c:int send_message_to_app(unsigned short message)
drivers/qnap/pic-arm.c:int send_message_to_app_qraid1(unsigned char message)
drivers/qnap/pic-arm.c:EXPORT_SYMBOL(send_message_to_app);
drivers/qnap/pic-arm.c:EXPORT_SYMBOL(send_message_to_app_qraid1);
drivers/qnap/qfunc.c: send_message_to_app_qraid1(rsync_path_id);
include/qnap/sendmessage.h:int send_message_to_app_qraid1(unsigned char message);
include/qnap/pic.h:int send_message_to_app(unsigned short message);

so why isn't referenced? Thanks for help! Regards.
