commit 2588aba002d14e938c2f56d299ecf3e7ce1302a5 upstream.
pch_uart_interrupt() takes priv->port.lock which leads to two recursive
spinlock calls if low_latency==1 or CONFIG_PREEMPT_RT_FULL=y (one
otherwise):
pch_uart_interrupt
spin_lock_irqsave(priv->port.lock, flags)
case PCH_UART_IID_RDR_TO

The following patch has been included in linux-next
(fe89def79c48e2149abdd1e816523e69a9067191) but has not yet landed in mainline
nor been queued for stable so far as I can determine. This patch addresses a
deadlock in mainline and is a prerequisite for an additional fix required by the
PREEMPT_RT
