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?
