💀 BUGS 💀

• The sony driver just parses integer values from the acpi(4) tree. It could be more intelligent and parse other controls. 😭
• The sysctl(8) interface is not great. The names of the sysctl(8) tree are not self-explanatory. 🙈
• No validity checks are performed on the user input. Playing with random values and/or unknown controls can harm your machine. ⚠️
• The name of the driver is too generic. 💀
