i hope so

honestly, this is the only bit that matters ... if someone wants to
run an older kernel but you're only interested in maintaining
mainline, then those people be damned.  stop using older kernels.

as long as you're completely aware and OK with the situation, then
let's stop talking about proposing for inclusion and post for review
already

wrt coding style, ive seen plenty of proposed things that were much
worse ... i dont think it'd take too much work to fix it ... you
should start with:
sed -i 's:[[:space:]]*$::' fs/yaffs*/*.c
