[ Upstream commit adfc8f9d2f9fefd880abc82cfbf62cbfe6539c97 ]
SERIAL_CORE_CONSOLE depends on TTY so EARLY_PRINTK should also depend on TTY so that it does not select SERIAL_CORE_CONSOLE inadvertently.
WARNING: unmet direct dependencies detected for SERIAL_CORE_CONSOLE Depends on [n]: TTY [=n] && HAS_IOMEM [=y] Selected by [y]: - EARLY_PRINTK [=y]

This is useful for kernel debugging when your machine crashes very early before the console code is initialized. You should normally say N here, unless you want to debug such a crash.
