From 108b5c8bba6be101100596bf37a165214e1c8458 Mon Sep 17 00:00:00 2001 From: Shawn Lin Date: Thu, 10 Mar 2016 14:52:27 +0800 Subject: [PATCH] spi: rockchip: covert rsd_nsecs to u32 type rsd_nsecs is defined as u8 memeber of struct rockchip_spi, but using of_property_read_u32. That means we take risk of truncation by type conversion if we pass on big value from dt.
