---
The sleep variable in inv_icm45600_buffer_postdisable could be used without being
assigned in case f error. It must be initialized to 0 by default.

Sorry, but you must write the commit message.

Why is this in the comment and not in the commit message? Also, can you spell
out the real compilation warning or so?

Otherwise the code might look okay, depending on the context. Again, usually
it's recommended to assign as late as possible to avoid subtle mistakes when
the same variable might be reused in the (future) code.
