2019-03-12ASoC: core: Fix panic when two cards register using the same daiSugar Zhang
This issue was caused by two cards using the same dai(cpu_dai/codec_dai). the second one will fail to register as a card, then will release the same dai resource, leading to the first card crash.

2019-01-15ASoC: rk3308_codec: fix some skip grps errorsXing Zheng
If we use the channels which are less than en_always_grps_num, we don't need to set the flag to skip_grps which are not used. And, the skip grps need to refer to mapped_grps For example, if: rockchip,en-always-grps = <1 2 3>; rockchip,adc-grps-route = <2 1 3 0>; The DUT startup and capture 2ch at first, we just open grp2 and set skip_grp[2]=1. Then, if we capture 4ch, we just skip grp2, open grp1, and set skip_grp[1]=1. To capture 6ch: we skip grp2/grp1, open grp3 and set skip_grp[3]=1. To capture 8ch: we skip grp2/grp1/grp3 and open grp0.

2018-12-05ASoC: rockchip: i2s_tdm: Correct some regmap configSugar Zhang
When restoring registers during runtime resume, we must not write to I2S_TXDR which is the transmit FIFO as this queues up a sample to be output and pushes all of the output channels down by one. This can be demonstrated with the speaker-test utility: for i in a b c; do speaker-test -c 2 -s 1; done which should play a test with through the left speaker three times but if the I2S hardware starts runtime suspended the first sample will be played through the right speaker. Fix this by marking I2S_TXDR as volatile (which also requires marking it as readable, even though it technically isn't). This seems to be the most robust fix, the alternative of giving I2S_TXDR a default value is more fragile since it does not prevent regcache writing to the register in all circumstances. While here, also fix the configuration of I2S_RXDR and I2S_FIFOLR; these are not writable so they do not suffer from the same problem as I2S_TXDR but reading from I2S_RXDR does suffer from a similar problem.

2018-10-10ASoC: dapm: Fix potential DAI widget pointer deref when linking DAIsLiam Girdwood
[ Upstream commit e01b4f624278d5efe5fb5da585ca371947b16680 ] Sometime a component or topology may configure a DAI widget with no private data leading to a dev_dbg() dereferencne of this data. Fix this to check for non NULL private data and let users know if widget is missing DAI.
