sdw_stream_add_slave/master have flags to indicate if the master or slave runtime where allocated in that call to the function. Currently these flags are cleared on all the paths where the runtime is not allocated, it is more logic and simpler to set the flag on the one path where the runtime is allocated. Signed-off-by: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxx> --- Changes since v1: - Split out of the goto patch to ease review Also worth noting I guess this patch could be squashed with patch 1 in the series really, but I opted to leave them separate as patch 1 is a much simpler fix to be cherry-picked back to older kernels if someone needs the fixup, rather than mixing the fixup and tidy up.
