[PATCH 08/20] media: iris: Skip flush on first sequence change

From: Dikshita Agarwal
Date: Tue Apr 08 2025 - 12:02:56 EST


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.
