Subject: media: venus: fix multiple encoder crash Author: Mansur Alisha Shaik mansur@codeaurora.org Date: Fri May 1 08:28:00 2020 +0200

Currently we are considering the instances which are available in core->inst list for load calculation in min_loaded_core() function, but this is incorrect because by the time we call decide_core() for second instance, the third instance not filled yet codec_freq_data pointer.

Solve this by considering the instances whose session has started.
