+ return -EINVAL;
+
+ if (mutex_lock_interruptible(&d->i2c_mutex) < 0)
+ return -EAGAIN;
+
+ for (i = 0; i < num; i++) {
+ if (msg[i].flags & (I2C_M_NO_RD_ACK | I2C_M_IGNORE_NAK
| I2C_M_TEN | I2C_M_NOSTART) || msg[i].len == 0) {
+ ret = -ENOTSUPP;
+ goto unlock;
+ }
+ if (i+1 < num && msg[i+1].flags & I2C_M_RD) {
+ if ((ret = m920x_read(d->udev,
M9206_TWALK_I2C_R,
+ msg[i].addr, msg[i].buf[0],
msg[i+1].buf, msg[i+1].len)) != 0)
+ goto unlock;
+ i++;
