What are the differences against sm1303? Why it cannot be merged there? You have entire commit msg to explain this instead of just sending empty commit.
I will add a commit message in the next version of the patch.
and where is the changelog? Why do you send the same code as v2?

Sorry, but why? What is so broken in this hardware that it requires such retries? Maybe just youro board is broken, not this codec?
Generally, if there are no issues, retries shold not occur and it should execute only once. Could this be a problem?
I included the retries because there might be issues with the connection.
Write code in uniform style to the rest of the kernel. If there is a problem, fix not only your but other users (BTW, might be already fixed in regmap). Therefore if you do not see any other regmap I2C drivers users doing this, that's a nice hint you are doing something maybe unnecessary.

Why do you cancel work in two different places?

Sorry. What does it mean?
Adjust to existing kernel style. git grep kzalloc. It means use dereference here.

Okay, When using 'Lindent', line breaks like this. I'll review and fix this. Thanks!

Drop, useless. Also does not match your I2C ID table.
The SMA1307A and SMA1307AQ are different chips with different device settings. Therefore, when registering in the devicetree, I intended to register the specific product and Cofigure the device settings accordingly.
Then why match data is the same? If it is the same, then most likely it is pointless. Otherwise why the differences are not visible in match data or usage of compatible? If devices are compatible, make them so and drop it.
I set the I2C ID table to just 'sma1307' as shown. So, should I change it to 'sma1307a' and 'sma1307aq instead?
Anyway, bindings are before their users.
Here you have answer to your other question.
