Subject: kernel: kmod-zram: break the strict dependency from lz4
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=99dae00fa86203effc3e7e41cbc8d89b9518848c;p=openwrt%2Fstaging%2Frobimarko.git

kernel: kmod-zram: break the strict dependency from lz4

Zram is only strictly dependent on lzo, not lz4. Break this dependency and
make the lz4 module visible in the configuration, in order for the user to
have the choice of enabling/disabling it, if (s)he sees fit.
