[PATCH 1/6] platform/x86: dell-smo8800: Only load on Dell laptops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The SMO8xxx ACPI HIDs are generic accelerometer ids which are also used
by other vendors. Add a sys_vendor check to ensure that the dell-smo8800
driver only loads on Dell laptops.
