Subject: media: i2c: imx219: Drop check for reentrant .s_stream()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fcf877f19165dadb2e0c9e631b4cb7027f24ec86;p=linux.git

media: i2c: imx219: 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.
