[PATCH 5.10 562/663] media: i2c: max9286: fix access to unallocated memory

[Greg Kroah-Hartman]

From: Tomi Valkeinen <tomi.valkei...@ideasonboard.com>

commit e88ccf09e79cf33cac40316ba69c820d9eebc82b upstream.

The asd allocated with v4l2_async_notifier_add_fwnode_subdev() must be
of size max9286_asd, otherwise access to max9286_asd->source will go to
unallocated memory.

Fixes: 86d37bf31af6 ("media: i2c: max9286: Allocate v4l2_async_subdev 
dynamically")
