From aa2af4f9994e6209e4b01d259ae67afb5c87e459 Mon Sep 17 00:00:00 2001

Subject: [PATCH] media: irs1125: Atomic access to imager
reconfiguration
Instead of changing the exposure and framerate settings for all sequences,
they can be changed for every sequence individually now. Therefore the
IRS1125_CID_SAFE_RECONFIG ctrl has been removed and replaced by
IRS1125_CID_SAFE_RECONFIG_S<seq_num>_EXPO and *_FRAME ctrls.
The consistency check in the sequence ctrl IRS1125_CID_SEQ_CONFIG
is removed.
