The reason that IOCTL to kernel give error "not a typewriter" in android source code

I prepare some IOCTL interfaces at kernel module of android. Then at android source code I open file dicriptor(fd) with path /proc/aaa and call desire ioctl with this fd. It is working well when I run a app on android. But it will give me the error 25 not a typewriter when I run a Pubg game on android. I trace with dmesg and figure out that ioctl in this case are not called at all. I test changing major number for my defined IOCTL but it didnt works. Could any body help me to debug and find the solution.

Thanks,Ehsan
