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 in the staging-testing branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Since wilc_set_multicast_list() is called with dev->addr_list_lock spinlock held, we can't use GFP_KERNEL memory allocation.
