isa: Implement the module_isa_driver macro (339e6e31) · Commits · 戴 / test

The module_isa_driver macro is a helper macro for ISA drivers which do not do anything special in module init/exit. This eliminates a lot of boilerplate code. Each module may only use this macro once, and calling it replaces module_init and module_exit. Signed-off-by:
