[PATCH 5.1 04/30] staging: wilc1000: Avoid GFP_KERNEL allocation from atomic context.

[Greg Kroah-Hartman]

From: Tetsuo Handa <penguin-ker...@i-love.sakura.ne.jp>

commit ae26aa844679cdf660e12c7055f958cb90889eb6 upstream.

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