[PATCH 0/3] ASoC: qcom: misc fixes for LPASS driver

[wangdich9700]

From: wangdicheng <wangdicheng@kylinos.cn>

A few small fixes for the Qualcomm LPASS ASoC driver:

  - Fix "LPASS_CDC_DMA_VA_TX0 ... LPASS_CDC_DMA_VA_TX0" case ranges
    that only matched VA_TX0, so VA_TX1..VA_TX8 hit the default case.
    In lpass-cdc-dma.c the va_mem0 clock was also not prepared for
    those DAIs.

  - Fix a misleading error message in lpass-hdmi.c that reported an
    invalid bit width when an unsupported sample rate was given.

  - Fix stray double spaces and blank lines.

[PATCH 2/3] ASoC: qcom: lpass-hdmi: fix invalid rate error message

[wangdich9700]

From: wangdicheng <wangdicheng@kylinos.cn>

The sampling rate switch reused the bitwidth error path, so an
unsupported rate logged "invalid bit width" with the bitwidth value.
Print the rate instead.

rate is unsigned; I am surprised you don't get compiler warnings about
that.

[PATCH 3/3] ASoC: qcom: fix VA CDC DMA DAI range handling

[wangdich9700]

From: wangdicheng <wangdicheng@kylinos.cn>

Several switch statements used "LPASS_CDC_DMA_VA_TX0 ...
LPASS_CDC_DMA_VA_TX0" which only matches VA_TX0, leaving VA_TX1
through VA_TX8 to hit the default case and print a spurious error.
In lpass-cdc-dma.c this also meant the va_mem0 clock was not
prepared for those DAIs. Use LPASS_CDC_DMA_VA_TX8 as the upper bound
to match the rest of the driver.
