ARM: pxa: fix dm9000 platform data regression
Since dm9000 driver added support for a vcc regulator, platform data based platforms have their ethernet broken, as the regulator claiming returns -EPROBE_DEFER and prevents dm9000 loading. This patch fixes this for all pxa boards using dm9000, by using the specific regulator_has_full_constraints() function. This was discovered and tested on the cm-x300 board. Fixes: 7994fe55a4a2 ("dm9000: Add regulator and reset support to dm9000") Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Acked-by: Igor Grinberg <grinberg@compulab.co.il>
