Subject: [PATCH] wd719x: pass GFP_ATOMIC instead of GFP_KERNEL
Date: Wed, 29 May 2019 07:05:40 +0530	[thread overview]
Message-ID: <20190529013540.GA20273@hari-Inspiron-1545> (raw)

wd719x_chip_init is getting called in interrupt disabled
mode(spin_lock_irqsave) , so we need to GFP_ATOMIC instead
of GFP_KERNEL.
