[PATCH] tty: serial: bcm63xx: use more precise Kconfig symbol

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Rafał Miłecki <rafal@xxxxxxxxxx>

Patches lowering SERIAL_BCM63XX dependencies led to a discussion and
documentation change regarding "depends" usage. Adjust Kconfig entry to
match current guidelines. Make this symbol available for relevant
architectures only.
