ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

regmap: split up regmap_config.use_single_rw Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.
