[PATCH] Fix proc_file_write missing ppos update

From: Stefani Seibold
Date: Sat Aug 29 2009 - 12:38:18 EST

The following fix a long standing issue in the proc_file_write function,
which doesn't update the ppos file position pointer.

This prevent the usage of multiple sequently writes on an opened proc
file, because it is impossible to distinguish these due the offset is
always 0.

The patch has no side effects, because the old implementaion has
no ability to access the file offset pointer.

Out of tree should work, also if there not using the new prototype definition,
because the new file offset pointer argument will be passed as last parameter.

The patch is against 2.6.31-rc8
