[PATCH 0/4] module autoloading fixes

[Zhang Rui]

Hi, all,

This patch set fixes a couple of module autoloading problem.

Patch 1/4 fixes a bug in ACPI device 'modalias' and 'uevent' attributes,
          although the bug can rarely be reproduced (only if there is an
          output error of snprintf, or the ids are longer than 1024 bytes)
Patch 2/4 introduces two new APIs for exporting ACPI style 'modalias' and
          'uevent' attributes in other buses.
Patch 3/4 introduce support for ACPI style 'modalias' and 'uevent'
          attributes in platform, I2C and SPI bus.
Patch 4/4 add OF style 'modalias' support for platform bus.

I did some tests and can confirm that the code for ACPI enumerated platform
bus device works well.
I tried with a patch with convert ACPI Fan device/driver to platform bus,
and can confirm that the code for ACPI enumerated platform device works well,
both the platform Fan driver and device show their modalias as "acpi:PNP0C0B".

thanks,
rui
