NFC 4.6 pull request

Browse Source 
This is a very small one this time, with only 5 patches.
 There are a couple of big items that could not be merged/finished
 on time.
 
 We have:
 
 - 2 LLCP fixes for a race and a potential OOM.
 - 2 cleanups for the pn544 and microread drivers.
 - 1 Maintainer addition for the s3fwrn5 driver.
