Hi Alain

Fixes tag is missing in your patch.
[ i.e ==> Fixes: aeb068c57214 ("i2c: i2c-stm32f7: add driver") ]

Nonetheless patch only consists in removing a comment character ?

Thanks

Hi Pierre-Yves,

thanks for the comments.

Okay, will push a v2 for that.

Yes, the comment currently starts in a way of a kernel-doc description
(https://www.kernel.org/doc/html/latest/doc-guide/kernel-doc.html#function-documentation) leading the compiler to produce the warning since there is no
function prototype after the comment.

Regards,
Alain
