When i make this gadget driver as built in, no issue in compiling kernel. But when i make this gadget driver as mdoule and compile the kernel, uImage is build suceesfully but gadget .ko is not made. One error come "FATAL: modpost: GPL-incompatible module g_drm.ko uses GPL-only symbol 'dev_driver_string'"
g_drm.c is the gadget driver file.
Complete log is as following:
LD arch/arm/boot/compressed/vmlinux
OBJCOPY arch/arm/boot/zImage
Kernel: arch/arm/boot/zImage is ready
Building modules, stage 2.

FATAL: modpost: GPL-incompatible module g_drm.ko uses GPL-only symbol 'dev_driver_string'
