* ASoC: sti: Fix error handling if of_clk_get() failsDan Carpenter2017-04-301-1/+1
| | | | | | | | | | We intended to return here. The current code has a static checker warning because we set "ret" but don't use it. Fixes: 76c2145ded6b ("ASoC: sti: Add CPU DAI driver for playback") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Arnaud POULIQUEN <arnaud.pouliquen@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: STI: Fix null ptr deference in IRQ handlerArnaud Pouliquen2017-04-063-15/+45
| | | | | | | | | | | | | | | With RTlinux a race condition has been found that leads to NULL ptr crash: - On CPU 0: uni_player_irq_handler is called to treat XRUN "(player->state == UNIPERIF_STATE_STOPPED)" is FALSE so status is checked, dev_err(player->dev, "FIFO underflow error detected") is printed and then snd_pcm_stream_lock should be called to lock stream for stopping. - On CPU 1: application stop and close the stream. Issue is that the stop and shutdown functions are executed while "FIFO underflow error detected" is printed. So when CPU 0 calls snd_pcm_stream_lock, player->substream is already null.

* ASoC: sti: unip reader tdm modeMoise Gergaud2016-04-121-61/+168
| | | | | | | | | | | | | | Here are the changes to enable reader tdm mode: - When TDM_ENABLE is set to 1, the i2s format should be automatically configured. Unfortunately this is not the case (HW bug). Then, we shall force DATA_SIZE setting. - Compute the transfer size for tdm mode: transfer size = user frame size - Manage tdm slots configuration given in DT. - Refine the hw param (channels & format) according to tdm slot config.
