2014-02-10spi: Use reinit_completion at appropriate placesAxel Lin
Calling init_completion() once is enough. For the rest of the iterations, call reinit_completion() instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-12-09spi: bcm63xx-hsspi: checking for ERR_PTR instead of NULLDan Carpenter
devm_request_and_ioremap() returns NULL on error, it doesn't return an ERR_PTR(). This patch fixes it by switching to devm_ioremap_resource() which is the prefered function anyway.

2013-12-04spi: bcm63xx-hsspi: add bcm63xx HSSPI driverJonas Gorski
