7.3-rc1 is free of calls to irq_domain_add_linear(), so it can be
deleted at last.
According to Dongliang Mu, the paragraph in the Chinese docs is now
obsolete. So drop it completely.

The very same patch just with "[patch V2]" was sent by you _one_ second
before this one.

tl;dr You can ignore '[PATCH]' and look at '[PATCH v2]' only. Do you
want me to send v3 properly?
I omitted `-1` to `git send-email` when sending
`./v2-0001-irqdomain-Delete-irq_domain_add_linear.patch`. So it sent
both '[PATCH]' and '[PATCH v2]'. With the same content.
thanks,

irqdomain: Delete irq_domain_add_linear()
7.3-rc1 is free of calls to irq_domain_add_linear(), so it can be finally
deleted.
According to Dongliang Mu, the related paragraph in the Chinese docs is now
obsolete. So drop it completely.
