Subject[PATCH] serial: 8250: remove Kconfig indirection
Date
Remove CONFIG_SERIAL_DETECT_IRQ and CONFIG_SERIAL_MANY_PORTS, and
substitute all references to the proper 8250 Kconfig options. Now, the
actual Kconfig dependencies are not hidden when reading the code and
static analyzers are less confused.
