Subject: msdos fs: remove unsettable atari option
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7557bc66be629d19a402e752673708bfbb8b5e86;p=openwrt%2Fstaging%2Fblogic.git

msdos fs: remove unsettable atari option

It has been impossible to set the option 'atari' of the MSDOS filesystem
for several years.  Since nobody seems to have missed it, let's remove its
remains.
