Hi,
This patch updates the Sony Programmable I/O Controller driver
for the Vaio laptops by:
- adding support for newer R505 series (credits go to
Michael Ashley <[EMAIL PROTECTED]>)
- adding two ioctl commands for getting/setting the
brightness on those laptops
- new module parameter for specifying if a camera should
be initialized (to be used on PictureBook series)
- small fix in the event processing logic
Alan, please apply.
Thanks,
Stelian.
