Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. In the case of some code where it is modular, we can extend that to also include files that are building basic support functionality but not related to loading or registering the final module; such files also have no need whatsoever for module.h The advantage in removing such instances is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h might have been the implicit source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each instance for the presence of either and replace/add as needed. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. Build coverage of all the mips defconfigs revealed the module.h header was masking a couple of implicit include instances, so we add the appropriate headers there.

|
* 1. Probe driver for the Malta's UART ports:
|
|
*
|
|
* o 2 ports in the SMC SuperIO
|
|
* o 1 port in the CBUS UART, a discrete 16550 which normally is only used
|
|
* for bringups.
|
|
*
|
|
* We don't use 8250_platform.c on Malta as it would result in the CBUS
|
|
* UART becoming ttyS0.
|
|
*
|
|
* 2. Register RTC-CMOS platform device on Malta.
