linux-5.10-rock-5-latest: clk DebugFS is enabled in the kernel #48

Open jrstarke opened 1 year ago

jrstarke commented 1 year ago

I originally raised this in https://github.com/radxa/kernel/issues/46, but they pointed out that this was fixed in https://github.com/radxa-repo/bsp/blob/main/linux/rockchip/0100-vendor/0008-Revert-ANDROID-clk-Enable-writable-debugfs-files.patch, so I can only assume that this means that the kernel package is out of date.

From my dmesg output, you can see the notice saying that clk debug is enabled. You can also see from my uname and apt install output, that I'm running the latest packages.
