I have read that article in ArchWiki. I understand that point that MIT licences are all custom because of individual copyright line. But then I do not understand when should I use license=('MIT') instead of license=('custom')?
I have read that MIT is a set of licenses, but it is kinda unclear. I guess that if there is clear text that it is a MIT license, then I use MIT, otherwise for MIT-style licence I just use custom. Am I correct?

>> Hello. I was repacking amdgpu-pro deb files and when I started converting licences, I have noticed that libdrm* packages have a MIT Licence text in copyright file. I decided to check if AUR/libdrm-git and Extra/libdrm uses MIT licence, but they don't. I contacted Lone_Wolf (maintainer of libdrm-git) and he said that he used a licence from Extra/libdrm.
