From 162f8debc01f48ac984ed6d7291743053ec90271 Mon Sep 17 00:00:00 2001 From: Maxime Chevallier Date: Wed, 24 Jan 2018 15:10:47 +0100 Subject: spi: a3700: Remove endianness swapping functions when accessing FIFOs Fixes the following sparse warnings : line 504: warning: incorrect type in assignment (different base types) line 504: expected unsigned int [unsigned] [usertype] val line 504: got restricted __le32 [usertype] line 527: warning: cast to restricted __le32 This is solved by removing endian-converson functions, since the converted values are going through readl/writel anyway, which take care of the conversion.
