On PTP mlx5_ptp_enable(on=0) flow, driver mistakenly used channel index as pin index. After ptp patch marked in fixes tag was introduced, driver can freely call ptp_find_pin() as part of the .enable() callback. Fix driver mlx5_ptp_enable(on=0) flow to always use ptp_find_pin(). With that, Driver will use the correct pin index in mlx5_ptp_enable(on=0) flow. In addition, when initializing the pins, always set channel to zero. As all pins can be attached to all channels, let ptp_set_pinfunc() to move them between the channels. For stable branches, this fix to be applied only on kernels that includes both patches in fixes tag. Otherwise, mlx5_ptp_enable(on=0) will be stuck on pincfg_mux. Fixes: 62582a7e ("ptp: Avoid deadlocks in the programmable pin code.") Fixes: ee7f1220 ("net/mlx5e: Implement 1PPS support") Signed-off-by:
