The driver overrides the error codes returned by platform_get_irq() to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream. IRQ0 is no longer returned by platform_get_irq(), so we now can safely ignore it... Fixes: 9ec36cafe43b ("of/irq: do irq resolution in platform_get_irq") Signed-off-by: Sergey Shtylyov <s.shtylyov@omp.ru> --- Changes in version 3: - corrected the "Fixes:" tag. Changes in version 2: - updated the patch description on treating IRQ0. drivers/usb/musb/musb_core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
