6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hangbin Liu <liuhangbin@xxxxxxxxx>
[ Upstream commit 5384cc0d1a88c27448a6a4e65b8abe6486de8012 ]
When getting kernel version via make, the result may be polluted by other
output, like directory change info. e.g.
$ export MAKEFLAGS="-w"
$ make kernelversion
make: Entering directory '/home/net'
6.8.0
make: Leaving directory '/home/net'
This will distort the reStructuredText output and make latter rst2man
failed like:
[...]
bpf-helpers.rst:20: (WARNING/2) Field list ends without a blank line; unexpected unindent.
[...]
Using silent mode would help. e.g.
$ make -s --no-print-directory kernelversion
6.8.0
Fixes: fd0a38f9c37d ("scripts/bpf: Set version attribute for bpf-helpers(7) man page")
