So for wireless and wireless-next I now check W=1 warnings every time I
push. We are mostly warning free now but I'm not checking the linker
warnings, for example the current MODULE_DESCRIPTION() warnings.

It's really annoying, and extra work, that people enable new W=1
warnings before fixing them. Could we somehow push back on those and
require that warnings are fixed before enabling with W=1 level?

In wireless there is a significant number of sparse warnings. I have
tried the cleanup people to fix them but it seems there's no interest,
instead we get to receive pointless cleanups wasting our time. <loud sigh>

BTW the 'no new line at end of file' warning is indeed from sparse, like
Arend suspected:

drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil.c:432:49: warning: no newline at end of file
