Critical fix for rtlwifi

[Larry Finger]

Kalle,

On November 18th, I submitted a patch entitles "[PATCH 4.20] rtlwifi: Fix leak 
of skb when processing C2H_BT_INFO" that fixes an skb memory leak.

I just checked, and this one-line patch is still sitting in patchwork with a 
status of "NEW". Why is this the case? The reports and testing of the fix took 
place in a GitHub issue thread, but that should not keep a critical fix from 
being handled fairly quickly. Meanwhile users of unpatched kernels are having 
their systems run out of memory! This problem is present in kernels 4.18+!
