staging: most: compress return logic into one line

Eliminate local variable 'ret' and modify return statement to contain
the value being returned directly instead of assigning it first to 'ret'
and returning this variable.

Coccinelle semantic patch used:
@@ expression e, ret; @@
-ret =
+return
	e;
-return ret;
