Subject: spi: spi-s3c64xx: Use module_platform_driver()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=50c959fc3366693174cdf3f1c82d0c01bbee926f;p=deliverable%2Flinux.git

spi: spi-s3c64xx: Use module_platform_driver()

subsys_init_call() initializes driver too early.
It's preventing to move DMA channel allocation at the begining
(driver probe).

This patch reduces and simplifies initalization code by
using module_platform_driver() macro.
It's also efficiently delaying driver startup.
