Subject[PATCH 6/8] tty: serial: Make SERIAL_SAMSUNG=y impossible when EXYNOS_USI_V2=m
Date
When UART is encapsulated in USIv2 block (e.g. in Exynos850), USIv2
driver must be loaded first, as it's preparing USI hardware for
particular protocol use. Make it impossible for Samsung serial driver to
be built-in when USIv2 driver is built as a module, to prevent incorrect
booting order for those drivers.
