The driver might skip the ov08x40_identify_module() on probe() based on
the acpi_dev_state_d0() check done in probe().

If the ov08x40_identify_module() call is skipped on probe() it should
be done on the first stream start. Add the missing call.

Note ov08x40_identify_module() will only do something on its first call,
subsequent calls are no-ops.

I'll add:

Cc: stable@xxxxxxxxxxxxxxx

Sounds good, thank you.

That is when you say "I'll add", you mean you'll add those tags
while merging this series, right ?

Or do you want me to the tags in a v3 series?

No need for v3. Thanks!

Are there other patches not merged for the driver, besides this set? No?

Bryan was talking about a fix from him which also needs to be merged:

https://git.codelinaro.org/bryan.odonoghue/kernel/-/commit/f10539a3cbe5c072829b082683f0d1393a7e50dc

But I cannot find that in the lore archives.

Bryan, did you ever post that fix ?

Regards,

Hans



Yep, it would be nice to place that patch first as patch #3 in this series
conflicts with it.

I've fixed up the tree here:

https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/media-stage/master-ov08x40-integration?ref_type=heads

Hans's patches are in my tree already. Could you rebase yours on my devel
branch (tree at <URL:https://git.linuxtv.org/sailus/media_tree.git/>) and
post it?


https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/media-sailus/devel-ov08x40?ref_type=heads

Puts

https://git.codelinaro.org/bryan.odonoghue/kernel/-/commit/b8f7e192b6bf0b8859158fb2b28b479d5c389054

before

https://git.codelinaro.org/bryan.odonoghue/kernel/-/commit/9370a82094d47d0383b0d52681b6b3a8d711ef9e

So that the first patch can be applied to stable.
