- since now we don't need to print error messages if copy_to/from_gpa()
fails, then in many cases we can simplify the function return handling.
In the following example, my fix could change the 'ret' value from
the original '-1' to the actual errno returned from copy_to_gpa(). But
this is valid. Ideally we may replace all '-1' with the actual errno.
- if (copy_to_gpa() < 0) {
- pr_err("error messages");
- ret = -1;
- } else {
- ret = 0;
- }
+ ret = copy_to_gpa();
- in most cases, 'ret' is declared with a default value 0 or -1, then the
redundant assignment statements can be removed.
- replace white spaces with tabs.
