Marliere Date: Mon, 12 Feb 2024 20:05:02 +0000 (-0300) Subject: powerpc: pmac: make macio_bus_type const X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=112202f34e56cd475e26b2a461dd856ca7570ef9;p=linux.git powerpc: pmac: make macio_bus_type const Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the macio_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
