+Subject: [PATCH] tty: fix compiler error
+
+At least on tests running on Fedora rawhide following error could be
+seen:
+
+```
+  criu/tty.c: In function 'pts_fd_get_index':
+  criu/tty.c:262:21: error: initialization discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
+    262 |         char *pos = strrchr(link->name, '/');
+        |
+```
+
+This fixes it.
