mmc: davinci: remove incorrect NO_IRQ use
platform_get_irq() returns an error value on failure, not NO_IRQ, so the error handling here could never work. This changes the code to propagate the error value instead. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
