[BKPATCH 2.5.11] sonypi driver update

[BKPATCH 2.5.11] sonypi driver update

[Stelian Pop]

Hi,

This patch updates the sonypi driver to the latest 2.4 version, thus:
	* fixing an array memory leak
	* fixing the order and the syntax for the parameters 
	  on the kernel command line
	* allowing multiple processes to open the sonypi device.

Dave, please apply this to your tree and feed it to Linus on the
next patch feeding session :-)

Thanks,

Stelian.

 Several options can be passed to the sonypi driver, either by adding them
 to /etc/modules.conf file, when the driver is compiled as a module or by
 adding the following to the kernel command line (in your bootloader):
 
-	sonypi=minor[[[[[,camera],fnkeyinit],verbose],compat],nojogdial]
