Subject: 8139too: Use disable_irq_nosync() in rtl8139_poll_controller()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=205cd52bbee7fe6452912fe01ceade970bccc926;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

8139too: Use disable_irq_nosync() in rtl8139_poll_controller()

[ Upstream commit af3e0fcf78879f718c5f73df0814951bd7057d34 ]

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