+Subject: [PATCH 2/2] image-fit: don't set compression if it can't be read
+
+fit_image_get_comp() should not set value -1 in case it can't read
+the compression node. Instead, leave the value untouched in that case
+as it can be absent and a default value previously defined by the
+caller of fit_image_get_comp() should be used.
+
+As a result the warning message
+WARNING: 'compression' nodes for ramdisks are deprecated, please fix your .its file!
+no longer shows if the compression node is actually absent.
