| Subject: [PATCH] platform: x86: asus_acpi: world-writable procfs files |
| |
| commit 8040835760adf0ef66876c063d47f79f015fb55d upstream. |
| |
| Don't allow everybody to change ACPI settings. The comment says that it |
| is done deliberatelly, however, the comment before disp_proc_write() |
| says that at least one of these setting is experimental. |
