Subject: media: intel/ipu6: Fix a null pointer dereference in
ipu6_isys_query_stream_by_source
Author: Hao Ge <ge...@kylinos.cn>
Date: Fri Jun 7 16:25:42 2024 +0800
stream is NULL when source is less than 0 in
ipu6_isys_query_stream_by_source. It's a null pointer dereference.
Actually, this should be isys->adev->auxdev.dev.
Fixes: 3c1dfb5a69cf ("media: intel/ipu6: input system video nodes and buffer
queues")
