hi Nicolas, > + if (data->slot[0].wp_pin) > + at91_set_gpio_input(data->slot[0].wp_pin, 1); > +static struct mci_platform_data __initdata mci0_data = { > + .slot[0] = { > + .bus_width = 4, > + .detect_pin = AT91_PIN_PD10, > + .wp_pin = -1, > + }, Causes at91_set_gpio_input() to be called for pin -1. Which shouldn't be valid. AT91 platforms use 0 to indicate an un-connected GPIO pin, so the assignment of "wp_pin" should probably just be removed.
