Subject: [PATCH 01/55] 8139too: Use disable_irq_nosync() in rtl8139_poll_controller()

From: Ingo Molnar <[email-masked]>
Date: Wed, 2 May 2018 13:30:57 +0200

[ Upstream commit af3e0fcf78879f718c5f73df0814951bd7057d34 ]

Use disable_irq_nosync() instead of disable_irq() as this might be
called in atomic context with netpoll.
