From afc016d8360ceb19a1f37bf6579d5850d47d582d Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Thu, 28 Jun 2012 16:21:34 +0800 Subject: can: flexcan: use of_property_read_u32 to get DT entry value of_property_read_u32() can auto handle endian problems, use this function can make code clean and simple. No need to check return value here since the following got value check will handle this.
