ASoC: wm_adsp: fix memleak in wm_adsp_buffer_populate
[ Upstream commit 29046a78a3c0a1f8fa0427f164caa222f003cf5b ]
When wm_adsp_buffer_read() fails, we should free buf->regions.
Otherwise, the callers of wm_adsp_buffer_populate() will
directly free buf on failure, which makes buf->regions a leaked
memory.
