Subject: [PATCH] brcmfmac: Avoid GFP_ATOMIC when GFP_KERNEL is enough
Date: Mon, 19 Apr 2021 21:35:17 +0200	[thread overview]
Message-ID: <b6e619415db4ee5de95389280d7195bb56e45f77.1618860716.git.christophe.jaillet@wanadoo.fr> (raw)

A workqueue is not atomic, so constraints can be relaxed here.
GFP_KERNEL can be used instead of GFP_ATOMIC.
