Subject: base-files: clean up ubinized sysupgrade code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=de4b65a793f8b7222d19f7507e7d3d93a0677597;p=openwrt%2Fstaging%2Fnbd.git

Remove redundant check from nand ubinized sysupgrade code. This check
has already been done in the only caller of the affected function:
nand_do_upgrade.
