From 7566bcc76b15186172c4db0414cf30c8a61e4a73 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Thu, 18 Dec 2014 15:04:20 +0200 Subject: [PATCH] spi: pxa2xx: Move is_lpss_ssp() tests to caller Move is_lpss_ssp() tests from functions to caller. Although this aims to improve readability it also saves a few code bytes on x86.
