2021-01-11ASoC: wm_adsp: Fix uninitialized variable warningsRichard Fitzgerald
wm_adsp_read_data_word() used if (ret) to check for an error from wm_adsp_read_raw_data_block(). While this is perfectly valid, wm_adsp_read_raw_data_block() itself uses if (ret < 0) and three calls to wm_adsp_read_data_word() also use if (ret < 0). This creates an error check chain like this: 1st) if (ret < 0) return ret; 2nd) if (ret) return ret; 3rd) if (ret < 0) ... This can confuse the compiler into thinking that there are possible returns > 0 from the middle if() that are not handled by the final if(). If this was true it would lead to using uninitialized variables later in the outer function. Fix this by changing the test in wm_adsp_read_data_word() to be if (ret < 0).

2020-12-31ASoC: wm_adsp: Use snd_ctl_elem_type_t for control typesRichard Fitzgerald
Sparse will complain about trying to convert between values declared as snd_ctl_elem_type_t and other types. This patch converts to consistently use snd_ctl_elem_type_t for control type values. A __force cast is needed in a couple of cases where the control type value is parsed out of a DSP data block.

2020-12-31ASoC: wm_adsp: Only use __be32 for big-endian dataRichard Fitzgerald
This fixes some minor cases where u32 or unsigned int types were used to store big-endian data, and __be32 types used to store both big-endian and cpu-endian data. This was producing sparse warnings. Most cases resulted from using the same variable to hold the big-endian value and its converted cpu-endian value. These can be simply fixed by introducing another local variable, or avoiding storing the intermediate value back into the original variable. One special case is the raw_buf used in the compressed streams to transfer data from DSP to user-side. The endian conversion happens in-place (as there's no point introducing another buffer) so a cast to (__be32 *) is added when passing it to wm_adsp_read_raw_data_block().

2020-12-28ASoC: wm_adsp: Improve handling of raw byte streamsRichard Fitzgerald
As the register map is 16-bit or 32-bit big-endian, the 24-bit DSP words appear padded and with the bytes swapped. When reading a raw stream of bytes, the pad bytes must be removed and the data bytes swapped back to their original order. The previous implementation of this assumed that the be32_to_cpu() in wm_adsp_read_data_block() would swap back to little-endian. But this is obviously only true on a little-endian CPU. It also made two walks through the data, once to endian-swap and again to strip the pad bytes. This patch re-works the code so that the endian-swap and unpad are done together in a single walk, and it is not dependent on the endianness of the CPU. The data_word_size argument to wm_adsp_remove_padding() has been dropped because currently this is always 3.
