[OpenWrt-Devel] [PATCH] ramips:Fix mt7612 support for Xiaomi Mini.

[Roger Pueyo Centelles]

Hi,

I added some prints to the eeprom.c file and saw that in function:

static int mt76_get_of_eeprom(struct mt76_dev *dev, int len)
{
    int ret = -ENOENT;
#ifdef CONFIG_OF
    struct device_node *np = dev->dev->of_node;
    struct mtd_info *mtd;
    const __be32 *list;
    const char *part;
    phandle phandle;
    int offset = 0;
    int size;
    size_t retlen;

    dev_printk(KERN_INFO, dev->dev, "mt76_get_of_eeprom. Step 0 (before
!np)");

    if (!np)
        return -ENOENT;

    dev_printk(KERN_INFO, dev->dev, "mt76_get_of_eeprom. Step 0 (after
!np)");
[...]

if does not go further than (   if (!np)   ).

Any ideas?
