Not tested
static int vch_write_data(struct virtual_channel *vch, char *ptr, int len)
{
struct phy_device *phy = vch->phy;
while ((len - phy->max_length) > 0) {
gsm0710_write(vch, GSM0710_DATA, ptr, phy->max_length);
ptr += phy->max_length;
len -= phy->max_length;
}
gsm0710_write(vch, GSM0710_DATA, ptr, len);
return len;
}
