I would timeout, return an error and check for it...
here ...
ret = mfrc522_init(dev);
if (ret < 0)
{
return ret;
}
and here ...
ret = mfrc522_softreset(dev);
if (ret < 0)
{
return ret;
}
Change the return types too please.
int mfrc522_softreset(FAR struct mfrc522_dev_s *dev);
int mfrc522_init(FAR struct mfrc522_dev_s *dev);
Return OK if there are no errors.
