ASoC: qdsp6: q6asm-dai: Off by one in of_q6asm_parse_dai_data()
The q6asm_fe_dais[] array has MAX_SESSIONS (8) elements so the > comparison should be >= or we access one element beyond the end of the array. Fixes: 22930c79ac5c ("ASoC: qdsp6: q6asm-dai: Add support to compress offload") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mark Brown <broonie@kernel.org>
