[PATCH 0/5] Generalize module_platform_driver

From: Lars-Peter Clausen
Date: Wed Nov 16 2011 - 04:14:55 EST

Grant Likely recently introduced the module_platform_driver macro which can be
used to eliminate a few lines on boilerplate code in platform driver modules.
The same approach can be used to do the same for other bus type drivers.

The first patch of this series generalizes the module_platform_driver macro and
introduces the module_driver macro. It is similar to module_platform_driver
macro but has two additional parameters to pass in the driver register and
unregister function. The intend is that this macro is used to construct bus
specific macros for generating the driver register/unregister boilerplate code.

The next two patches in this series add the module_i2c_driver and
module_spi_driver macro which use the module_driver macro to generate the I2C
and SPI driver boilerplate code.

The last two patches convert the driver found in the IIO framework to use the
new module_i2c_driver and module_spi_driver macros to demonstrate their
potential and remove over 700 lines of code.

While this series only introduces these kind of helper macros for I2C and SPI
bus drivers the same scheme should be applicable to most other bus driver types.
For example PCI and USB seem to be good candidates.

It probably makes sense to merge the first three patches together. The last two
can probably, since this is not urgent, wait until the first three have reached
mainline.
