Subject: soc: fsl: cpm1: qmc: Check available timeslots in qmc_check_chans()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f2deea16bf187ad6e1f2a7b0d2fd0b1a4db0b1b7;p=linux.git

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().
