Subject: mac80211: use __printf attribute in debugfs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8c1dddd6070a900918561f162621ef4957ff36c2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mac80211: use __printf attribute in debugfs

The internal function mac80211_format_buffer() has a
printf-style argument list, so add the attribute to
have gcc verify that list.
