ASoC: wm_adsp: Interpret ADSP memory region lengths as 32 bit words
Pad the ADSP word (3 bytes) to 4 bytes in the kernel and calculate lengths based on padded ADSP words instead of treating them as bytes Signed-off-by: Nariman Poushin <nariman@opensource.wolfsonmicro.com> Signed-off-by: Dimitris Papastamos <dp@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org> Cc: stable@vger.kernel.org
