Subject: [PATCH AUTOSEL 4.20 012/105] mfd: at91-usart: Add platform dependency

From: Jean Delvare <jdelvare@...e.de>

[ Upstream commit 628f3dfe4c7b35bbe63ec194ca6da857b00b0083 ]

It doesn't make sense to present option MFD_AT91_USART by default if
not building an AT91 kernel, as the drivers which depend on it are
not available.

Fixes: 7d3aa342cef7 ("mfd: at91-usart: Add MFD driver for USART")
