Subject: Re: [PATCH v2 12/28] soc: fsl: cpm1: qmc: Check available timeslots
 in qmc_check_chans()

> The timeslots checked in qmc_check_chans() are the timeslots used.
> With the introduction of the available timeslots, the used timeslots
> are a subset of the available timeslots. The timeslots checked during
> the qmc_check_chans() call should be the available ones.
> 
> Simply update and check the available timeslots instead of the used
> timeslots in qmc_check_chans().
