In kernel menuconfig you can select if driver will be compiled like
module ([M] option)
or will be included in kernel ([*] option). If you select second
option your driver will be always
loaded. Be aware if your driver must be loaded before some other
drivers. But if no other
dependency it is sufficient.

I dont want to compile the whole kernel for this.

I have a complied version of the module in /etc/xyz/

and I want that the module gets inserted everytime the system boots

Create device node with command mknod /dev/abc c(for character device)
<major number> <minor mumber>
You need to be root to execute this command.

How to get the major and minor number when mknod is running automatically.

i can do a cat /proc/devices but I want it to be done automatically.

A grep | cut can also give the major and minor number but I wanted to know that

Is this the only way ??
