libxt_recent: Remove ineffective checks for info->name
|
|
|

|

9a3fa7 |
In struct xt_recent_mtinfo{,_v1}, field 'name' is an array, not a
|
|
|
9a3fa7 |
pointer. So there is no point in comparing it against NULL. Changing the
|
|
|
9a3fa7 |
check to make sure it's content is not an empty string is pointless
|
|
|
9a3fa7 |
either, since a non-empty default string is used and the argument parser
|
|
|
9a3fa7 |
will refuse empty strings as --name argument. So simply get rid of the
|
|
|
9a3fa7 |
checks altogether.
