If anyone has any objections, please let me know. ------------------ From: Artem Bityutskiy <artem.bityutskiy@...ux.intel.com> commit abb3e01103eb4e2ea5c15e6fedbc74e08bd4cc2b upstream. Currently UBI fails in autoresize when it is in R/O mode (e.g., because the underlying MTD device is R/O). This patch fixes the issue - we just skip autoresize and print a warning.
