Aaron Sierra 60ab0fafc4 serial: 8250_exar: Read INT0 from slave device, too ... The sleep wake-up refactoring that I introduced in commit c7e1b40590 ("tty: serial: exar: Relocate sleep wake-up handling") did not account for devices with a slave device on the expansion port. This patch pokes the INT0 register in the slave device, if present, in order to ensure that MSI interrupts don't get permanently "stuck" because of a sleep wake-up interrupt as described here: commit 2c0ac5b48a ("serial: exar: Fix stuck MSIs") This also converts an ioread8() to readb() in order to provide visual consistency with the MMIO-only accessors used elsewhere in the driver.
