This is a note to let you know that I've just added the patch titled
staging: wilc1000: Avoid GFP_KERNEL allocation from atomic context.
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

The patch will show up in the next release of the linux-next tree

Subject: staging: wilc1000: Avoid GFP_KERNEL allocation from atomic context.
Since wilc_set_multicast_list() is called with dev->addr_list_lock
spinlock held, we can't use GFP_KERNEL memory allocation.
