So, the error is on this patch? author Patrick Boettcher <pboettcher@xxxxxxxxxxxxxx> 2013-04-22 15:45:52 (GMT) [media] dib8000: enhancement The intend of this patch is to improve the support of the dib8000. Signed-off-by: Olivier Grenie <olivier.grenie@xxxxxxxxxx> Signed-off-by: Patrick Boettcher <patrick.boettcher@xxxxxxxxxx> Signed-off-by: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx> If so, then we need either Olivier or Patrick's help, as I don't have any documentation about the dib8000 chips. You can still take a look there at the code that checks for the chipset version, like: if (state->revision == 0x8090) { <some code for newer version> } else { <some code for the old version> } If the code for the old version remains the same as before the patch. Where it doesn't remains the same, then it could be the source of the troubles. I suggest you to check what state->revision shows on your specific device, in order to do such analysis. I'll try latter to do some tests with the devices I have, but this could take some time, as I'm really busy those days.
