[PATCH v2 09/23] media: iris: Skip flush on first sequence change
Posted by Dikshita Agarwal 9 months, 2 weeks ago
Add a condition to skip the flush operation during the first sequence
change event. At this point, the capture queue is not streaming, making
the flush unnecessary.

Additionally, remove the reinit_completion call for the flush completion
signal, as it is not needed. This simplifies the code and avoids
unnecessary reinitialization.
