[08/13] Input: touchscreen - Use local variables consistently

Commit Message

If a function declares a variable to access a structure element,
use it conssistently.

The conversion was done automatically with coccinelle using
the following semantic patch.

// Catch function parameters.
// Handle those first to trigger reformatting.

@@
identifier d;
identifier fn;
identifier svar;
identifier elem;
type T;
identifier i;
expression e;
identifier fn;
expression list es;
@@

fn(...) {
  ...
  T d = &svar->elem;
<... when != d = e;
- fn(&svar->elem, es)
+ fn(d, es)
...> }

// Now address non-functions and multiple transformations in function
// parameters.
