From 0e5c4b4d154ee0a34e39e1a587f71d4671783abf Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 18 Sep 2015 13:08:27 +0200 Subject: [PATCH] serial: sh-sci: Stop calling sci_start_rx() from sci_request_dma() There's no need to call sci_start_rx() from sci_request_dma() when DMA setup fails, as sci_startup() will call sci_start_rx() anyway.
