In imx477_start_streaming, when restarting before the auto-suspend timeout (5s) so that the common register config write was skipped, "ret" was used uninitialized, leading to intermittent failure. (Since return values are fully checked after the common write, there is anyway no need to propagate ret to mode-specific write.) Signed-off-by: Nick Hollinghurst <nick.hollinghurst@raspberrypi.com>

Should this not be back-ported to 6.12? |

Yes - I will do that. (Does it need a new PR, or any special note in the commit that it's a duplicate?) |

I'll cherry-pick it. This is a patch that will be carried forward by us, probably squashed, at least until it gets merged upstream. The only time we appreciate special comments in the commit message is when it is a backport of an upstream commit, and therefore something with a finite shelf life. |
