Subject: Re: [PATCH v3] media: hackrf: don't cluster controls before checking init failure
Date: Sun, 18 Oct 2026 14:56:38 -0000	[thread overview]

Hi,

Any chance of getting eyes on this one? It has been sitting for a couple of weeks.

The root cause is a NULL dereference: hackrf calls v4l2_ctrl_auto_cluster()
before checking the control handler's error state, so an allocation failure in
v4l2_ctrl_new_std() leaves a NULL master control behind. pwc-v4l.c already
guards the same class of problem.

Happy to rebase or reword.

Thanks,
Mimo
