| |
3.2.82-rc1 review patch. If anyone has any objections, please let me know.

From: William Breathitt Gray <vilhelm.gray@gmail.com>
commit 32a5a0c047343b11f581f663a2309cf43d13466f upstream.
The isa_bus_init function must be called before drivers which utilize the ISA bus driver are registered. A race condition for initilization exists if device_initcall is used (the isa_bus_init callback is placed in the same initcall level as dependent drivers which use module_init). This patch ensures that isa_bus_init is called first by utilizing postcore_initcall in favor of device_initcall.
