[PATCH v6 16/30] soc: fsl: cpm1: qmc: Check available timeslots in qmc_check_chans()

From: Herve Codina <herve.codina@bootlin.com>
Date: 2023-09-22 08:01:45
Also in: alsa-devel, linux-devicetree, linux-gpio, linuxppc-dev, lkml, netdev
Subsystem: freescale quicc engine library, freescale quicc engine qmc driver, freescale soc drivers, the rest · Maintainers: Qiang Zhao, Christophe Leroy, Herve Codina, Linus Torvalds

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().
