From: Uwe Kleine-König Date: Mon, 23 Jan 2023 22:02:21 +0000 (+0100) Subject: clocksource/drivers/sh_cmt: Mark driver as non-removable X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c3daa4754f3c57231bf47dcf4bdf897bc5c5f1f1;p=linux.git clocksource/drivers/sh_cmt: Mark driver as non-removable The comment in the remove callback suggests that the driver is not supposed to be unbound. However returning an error code in the remove callback doesn't accomplish that. Instead set the suppress_bind_attrs property (which makes it impossible to unbind the driver via sysfs). The only remaining way to unbind a sh_cmt device would be module unloading, but that doesn't apply here, as the driver cannot be built as a module. Also drop the useless remove callback.
