Subject: [PATCH 1/2] ASoC: qdsp6: q6asm-dai: Off by one in of_q6asm_parse_dai_data()
Date: Fri, 21 Dec 2018 12:04:42 +0300 [thread overview]
Message-ID: <20181221090442.GA2735@kadam> (raw)
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")
