In commitfec8fe8069("kernel: bump 4.9 to 4.9.116") [1], the following patch for removed: - 403-mtd_fix_cfi_cmdset_0002_status_check.patch This patch contained fixes for both write and erase functions. While the chip-detects for erase got fixed upstream [2], some modifications are still required, even with the fixes applied. While at it, also apply the same fix for target ath79, which suffers the same issue. Not doing so results in following errors seen: Collected errors: * pkg_write_filelist: Failed to open //usr/lib/opkg/info/luci-lib-ip.list: I/O error. * opkg_install_pkg: Failed to extract data files for luci-lib-ip. Package debris may remain! * opkg_install_cmd: Cannot install package luci-ssl. * opkg_conf_write_status_files: Can't open status file //usr/lib/opkg/status: I/O error.
