Subject: spi: pxa2xx: Move is_lpss_ssp() tests to caller
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7566bcc76b15186172c4db0414cf30c8a61e4a73;p=openwrt%2Fstaging%2Fblogic.git

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.
