[PATCH 1/2] serial: at91, fix rs485 properties

From: Jiri Slaby
Date: Sun Oct 11 2015 - 09:22:54 EST


There is a misplaced bracket in atmel_init_rs485 which sets
rs485-rx-during-tx and rs485-enabled-at-boot-time only if
rs485-rts-delay is set in of.

This is clearly a bug, so fix it by moving the bracket to the proper
place.
