ASoC is now unified asoc_xxx() into snd_soc_xxx(). This patch convert asoc_xxx() to snd_soc_xxx(). Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87bke8qnh3.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

The ASoC Sound Card driver can be compile tested with !CONFIG_OF making 'loongson_asoc_dt_ids' unused: sound/soc/loongson/loongson_card.c:200:34: warning: unused variable 'loongson_asoc_dt_ids' [-Wunused-const-variable] As krzysztof advice, we drop of_match_ptr so the device id can also be used on ACPI.

2023-06-22ASoC: loongson: fix address space confusionArnd Bergmann
The i2s driver uses the mapped __iomem address of the FIFO as the DMA address for the device. This apparently works on loongarch because of the way it handles __iomem pointers as aliases of physical addresses, but this is not portable to other architectures and causes a compiler warning when dma addresses are not the same size as pointers: sound/soc/loongson/loongson_i2s_pci.c: In function 'loongson_i2s_pci_probe': sound/soc/loongson/loongson_i2s_pci.c:110:29: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 110 | tx_data->dev_addr = (dma_addr_t)i2s->reg_base + LS_I2S_TX_DATA; | ^ sound/soc/loongson/loongson_i2s_pci.c:113:29: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] 113 | rx_data->dev_addr = (dma_addr_t)i2s->reg_base + LS_I2S_RX_DATA; | ^ Change the driver to instead use the physical address as stored in the PCI BAR resource directly. Since 'dev_addr' is a 32-bit address, I think this results in the same truncated address on loongarch but is otherwise closer to portable code and avoids the warning.

2023-06-20ASoC: loongson: use snd_soc_{of_}get_dlc()Kuninori Morimoto
Current ASoC has snd_soc_{of_}get_dai_name() to get DAI name for dlc (snd_soc_dai_link_component). But we now can use snd_soc_{of_}get_dlc() for it. Let's use it.

2023-06-19ASoC: loongson: change the type of variable irq to intYingKun Meng
We use variable 'irq' to store the return value of fwnode_get_irq_byname(). A negative value indicates that the operation failed. If the type of 'irq' is unsigned int, we never know if the operation failed.

2023-06-19ASoC: loongson: fix error codes in loongson_card_parse_acpi()Dan Carpenter
The acpi_node_get_property_reference() function returns kernel error codes and not ACPI error codes. So, although it does not affect the compiled code, using the ACPI_FAILURE() macro is wrong. Secondly, if the is_acpi_device_node() function returns false, then we should return -ENOENT instead of returning success.
