Subject: reset: meson: make it possible to build as a module
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3bfe8933f9d187f93f0d0910b741a59070f58c4c;p=linux.git

reset: meson: make it possible to build as a module

In order to reduce the kernel Image size on multi-platform distributions,
make it possible to build the reset controller driver as a module.

This partially reverts commit 8290924e6878 ("reset: meson: make it
explicitly non-modular").
