This is the resulting code:
if (p->flags & CLKFLAG_MIN)
rc = msm_proc_comm(PCOM_CLKCTL_RPC_MIN_RATE, &id, &rate);
else
rc = msm_proc_comm(PCOM_CLKCTL_RPC_SET_RATE, &id, &rate);
if (rc < 0)
return rc;
else
return (int)id < 0 ? -EINVAL : 0;
So we check the rc for both cases in the same if condition. Is there
anything wrong?
