knav_pool_create is an exported function. In the event of a call before knav_queue_probe, we encounter a NULL pointer dereference in the following line. Hence return -EPROBE_DEFER to the caller till the kdev pointer is non-NULL. Signed-off-by: Keerthy <j-keerthy@ti.com> --- Changes in v2: * Fixed returning an int to returning pointer.
FWIW, Acked-by: Santosh Shilimkar [off-list ref] Can you please also apply this fix in your fixes branch ?
