(c/c patch author, to be sure that he'll see your explanation request) His original patch is at: https://patchwork.kernel.org/patch/91929/ The original description with the bug were much better than version 2. >From his OOPS log and description, I suspect that he's facing some sort of race condition with the two cards. This fix seems still valid (with an updated comment), as his dump proofed that there are some cases where fe->tuner_priv can be null, generating an OOPS, but it seems that his patch is combating the effect, and not the cause. So, I am for adding his patch for now, and then work on a more complete approach for the two cards environment. -- Cheers, Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
