-Subject: [PATCH 311/454] sc16is7xx: Fix for "Unexpected interrupt: 8"
-
-The SC16IS752 has an Enhanced Feature Register which is aliased at the
-same address as the Interrupt Identification Register; accessing it
-requires that a magic value is written to the Line Configuration
-Register. If an interrupt is raised while the EFR is mapped in then
-the ISR won't be able to access the IIR, leading to the "Unexpected
-interrupt" error messages.
-
-Avoid the problem by claiming a mutex around accesses to the EFR
-register, also claiming the mutex in the interrupt handler work
-item (this is equivalent to disabling interrupts to interlock against
-a non-threaded interrupt handler).
-
-See: https://github.com/raspberrypi/linux/issues/2529
