Is this right? The comment on the field says "fifo entries of AC97/I2S PSC", which doesn't suggest bytes. The data sheet speaks of "words" and "byte masks", but without digging into it I can't tell how it would behave with different sample widths and channel counts (which the driver does not seem to limit _at all_? what am I missing?).
This is just something I stumbled over while surveying how different drivers set the field. If this is actually a bug, it is minor. --- sound/soc/au1x/dbdma2.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
