From bf5c004691d19adb900044f0696c4d1156881747 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 14 Sep 2023 21:16:19 +0300 Subject: media: i2c: imx412: Drop check for reentrant .s_stream() The subdev .s_stream() operation shall not be called to start streaming on an already started subdev, or stop streaming on a stopped subdev. Remove the check that guards against that condition. The streaming field of the driver's private structure is now unused, drop it as well.
