While there certainly are such cases, I think here it’s just about being proficient in a language. Pointers, referencing and dereferencing are the bread and butter of any C code, and applying them in a way to reduce complexity is certainly something to strive for - if this isn’t readable then I’d argue the reader shouldn’t be touching the codebase anyways.
Fortunately or unfortunately you don’t always get to decide who touches the code, so unless performance is a concern as it is in kernel development optimising like this in the day job will eventually lead people making mistakes. Basically I say be as explicit and clear as you dare, even at the cost of some CPU cycles.
