[PATCH] char: misc: minor code cleanup

[Martin Kaiser]

Fix a couple of minor issues found by checkpatch.pl:

Add/remove spaces where required.
Move EXPORT_SYMBOL() to the end of the function it refers to.
Set the access mode for the proc entry explicity.
Use pr_warn() instead of printk() without loglevel.
