[SOLVED] sysupgrade fails (xorg-server, xf86-input-libinput)

[mobrien]

The issue occures on an arm6h (raspberry pi model b) when trying to -Syu the system:
$this->bbcode_second_pass_code('', '
# pacman -Syu
:: Synchronizing package databases...
core is up to date
extra is up to date
community is up to date
alarm is up to date
aur is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: xf86-input-libinput and xorg-server are in conflict (X-ABI-XINPUT_VERSION>=23)
')

Interestingly "xf86-input-libinput" is not installed:

$this->bbcode_second_pass_code('', '
# pacman -Q | grep xf86-input-libinput
#
')

So I installed the package ...

$this->bbcode_second_pass_code('', '
# pacman -S xf86-input-libinput
resolving dependencies...
looking for conflicting packages...

Packages (1) xf86-input-libinput-0.22.0-1

$this->bbcode_second_pass_code('', '

... to strangely end up with the following:

Just want to confirm this is happening on rbpi3 and rbpi2 too, any tips for solutions appreciated.

EDIT: Fixed on recent update of xf86-video-fbdev and xf86-input-libinput
