+Subject: [PATCH 15/18] serial: pch: Don't disable interrupts while acquiring
+ lock in ISR.
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.8/older/patches-6.8.2-rt11.tar.xz
+
+The interrupt service routine is always invoked with disabled
+interrupts.
+
+Remove the _irqsave() from the locking functions in the interrupts
+service routine/ pch_uart_interrupt().
