The rmmod command in the example used a hyphen (hello-5), but Linux kernel module names conventionally use underscores (hello_5) to align with C identifier naming rules.
This change corrects the module name to use an underscore, ensuring the documentation is consistent and avoiding potential confusion for readers trying to run the command.
Summary by cubic
Correct the rmmod example to use hello_5 (underscore) instead of hello-5 (hyphen), aligning with kernel module naming rules and avoiding confusion when running the command.
