Defmt's dbg! implementation fails clippy::double_parens

[DusterTheFirst]

When using the dbg! macro in a function call, the macro expansion seems to flag a clippy lint. clippy::double_parens to be specific.

This is more of a clippy, than a defmt issue. In best case clippy would ignore lints from foreign macros, since as a user you have limited control over the expansion. See rust-lang/rust-clippy#407 for more information.

As a workaround you can silence the warning by adding an allow-statement before the macro call:

#[allow(clippy::double_parens)]
function(defmt::dbg!(a));
