A more correct reference would be, however, the index of each stream, instead. This patch corrects the check of bitmaps to the stream index. Note that this change doesn't fix anything for now; all existing drivers set up the stream indices properly, hence the loop count is always equal with the stream index. That said, this change is only for consistency.

The MAX means the maximum number of significant bits which can the physical format hold. For 32-bit formats, MAX is related to 32 bits. For 8-bit formats, MAX is related to 8 bits etc. As there is only one user currently (format S32_LE), subformat is represented by a simple u32 and stores flags only for that one user alone. The approach of subformat being part of struct snd_pcm_hardware is a compromise between ALSA and ASoC allowing for hw_params-intersection code to be alloc/free-less while not adding any new responsibilities to ASoC runtime structures.

Account for them to allow for granular format selection. As there is only one user currently (format S32_LE), subformat is represented by a simple u32 and stores flags only for that one user alone. Such approach allows for alloc/free-less code until there are more users on the horizon.

S20_LE, S24_LE and their unsigned and BE friends are invalid from HDAudio perspective but still can be specified as function argument due to compatibility reasons. snd_hdac_stream_format_bits() - obtain just the bits-per-sample value. Does not ignore subformat and msbits parameters. snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the SDxFMT value given the audio format parameters. The former is stripped away of spdif-related information. Useful for users that do not care about them.

Gen 4 devices have removed, moved, and new related controls, so this needs to be cleaned up. By adding SCARLETT2_CONFIG_MASTER_VOLUME (the only config item that didn't already have its own entry, because it is read-only), we can remove: - struct scarlett2_usb_volume_state, - #define SCARLETT2_USB_VOLUME_STATUS_OFFSET, and - scarlett2_usb_get_volume_status() and replace with calls to scarlett2_usb_get_config().

Note, this fixes a duplicate definition of ac97_bus_type, which somehow was declared extern in a .h file, and then static as a prototype in a .c file, and then properly later on in the same .c file.
