Subject: [PATCH] parisc: make parisc_bus_type const
Date: Tue, 13 Feb 2024 11:38:02 -0300 [thread overview]
Message-ID: <20240213-bus_cleanup-parisc-v1-1-2e61c77e66c6@marliere.net> (raw)
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 parisc_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.
