From: Ricardo B. Marliere Date: Sun, 3 Mar 2024 23:05:23 +0000 (-0800) Subject: Input: synaptics-rmi4 - make rmi_bus_type const X-Git-Tag: v6.9-rc1~78^2^2~10 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d1278c91fec3e1d27d6e06d00a67a5a314341344;p=thirdparty%2Flinux.git Input: synaptics-rmi4 - make rmi_bus_type const Now that the driver core can properly handle constant struct bus_type, move the variable rmi_bus_type to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
