+
+    Added sane_reload_devices() to sane_init().
+
+    Adding sane_reload_devices() to sane_init() required sane_init() to be moved
+    below the sane_reload_devices() declaration.  This restores the original
+    functionality present before I split the sane_reload_devices() code out of
+    sane_init() so that it could be called from sane_get_devices().
+    (cherry picked from commit 33bb529c5f8ca013fb499addc14c7fb229203ea8)
