Subject: mac80211: do not add debugfs_create_devm_seqfile() on recent kernel versions
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=91bdcc65e95476e473dfa35f9ad508e9bc29aeb6;p=openwrt%2Fstaging%2Fadrian.git

mac80211: do not add debugfs_create_devm_seqfile() on recent kernel versions

An #ifdef for the kernel version was missing around the header of
debugfs_create_devm_seqfile() and the LINUX_BACKPORT() was also not
done.

This closes #20181
