Subject: [PATCH] watchdog: pcwd_usb: Avoid GFP_ATOMIC where it is not needed
Date: Sun,  9 Aug 2020 09:19:12 +0200	[thread overview]
Message-ID: <20200809071912.742836-1-christophe.jaillet@wanadoo.fr> (raw)

There is no need to use GFP_ATOMIC here. It is a probe function, no
spinlock is taken and GFP_KERNEL is used just before and just after this
'usb_alloc_coherent()' call.
