Cássio Gabriel 5ed060d549 ALSA: aoa: i2sbus: clear stale prepared state ... The i2sbus PCM code uses pi->active to constrain the sibling stream to an already prepared duplex format and rate in i2sbus_pcm_open(). That state is set from i2sbus_pcm_prepare(), but the current code only clears it on close. As a result, the sibling stream can inherit stale constraints after the prepared state has been torn down. Clear pi->active when hw_params() or hw_free() tears down the prepared state, and set it again only after prepare succeeds. Replace the stale FIXME in the duplex constraint comment with a description of the current driver behavior: i2sbus still programs a single shared transport configuration for both directions, so mixed formats are not supported in duplex mode.
