This is a note to let you know that I've just added the patch titled

staging: rtl8188eu: Fix module loading from tasklet for CCMP

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

Subject: staging: rtl8188eu: Fix module loading from tasklet for CCMP
encryption

Commit 6bd082af7e36 ("staging:r8188eu: use lib80211 CCMP decrypt") causes scheduling while atomic bugs followed by a hard freeze whenever the driver tries to connect to a CCMP-encrypted network. Experimentation showed that the freezes were eliminated when module lib80211 was preloaded, which can be forced by calling lib80211_get_crypto_ops() directly rather than indirectly through try_then_request_module(). With this change, no BUG messages are logged.
