From 339e6e31d2bfb40354cbfe672b357b88a88223f2 Mon Sep 17 00:00:00 2001 From: William Breathitt Gray Date: Sun, 1 May 2016 18:42:47 -0400 Subject: [PATCH] isa: Implement the module_isa_driver macro 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.
