Summary
Go to packages.archlinux.org, type acpi_call in a search field, download and install acpi_call-dkms, remove all local acpi_call packages provided by Manjaro, install the one you have just downloaded with pacman -U %packagename% and forget about this problem 
Arch package should be perfectly compatible, same is applicable to bbswitch btw.
Yep, some unknown reasons make Manjaro devs do extra work on building a bunch of out-of-tree drivers for each kernel version instead of using dkms, and sometimes they do not update them in time.</>
Okay, so acpi_call-dkms in Manjaro repos is the same as in Arch repo. Just use it.
