Subject: [PATCH] staging:iio:adc:ad7280a: Use GFP_ATOMIC in interrupt handler
Date: Fri, 29 Jun 2018 01:55:03 +0200 [thread overview]
Message-ID: <20180628235503.4464-1-karim.eshapa@gmail.com> (raw)
Use GFP_ATOMIC rather GFP_KERNEL in interrupt handler,
as GFP_KERNEL may sleep according to slab allocator.
