Subject: kbuild: move warnings about linux/export.h from W=1 to W=2
X-Git-Tag: v6.16-rc2~1^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a6a7946bd691940cfe7289ae6dfb1f077516df72;p=thirdparty%2Fkernel%2Flinux.git

kbuild: move warnings about linux/export.h from W=1 to W=2

This hides excessive warnings, as nobody builds with W=2.

Fixes: a934a57a42f6 ("scripts/misc-check: check missing #include <linux/export.h> when W=1")
Fixes: 7d95680d64ac ("scripts/misc-check: check unnecessary #include <linux/export.h> when W=1")
