[PATCH] Added module params and fixed checkpath errors

[Sumya Hoque <sumyahoque2012@gmail.com>]

I’ve followed these steps to add module parameters and capture the dmesg output:

I included the module.h header and used the module_param() macro to take the argument value as input from the command line. At runtime, insmod will take the input for the "name" variable. The default value is "World" if no input is provided.

Dmesg Output:

[32002.988222] Removing module... Goodbye World!
[32026.041939] Loading module... Hello Sumya
