What actually happens is that both of those commands print 0 regardless of the hardware state. The cause is that wmi_query_block returns an ACPI_TYPE_INTEGER rather than ACPI_TYPE_BUFFER as the driver assumes. Additionally, the driver intends to return a jogdial state that is inverted with respect to the commands required to set it (e.g. it intends to return 1 after the jogdial file was written with 0). This patch fixes both of those issues - the commands to query the state now work, and should return the same state that was written. http://bugzilla.kernel.org/show_bug.cgi?id=12286 Signed-off-by: Krzysztof Kosiński Acked-by: Carlos Corbacho Signed-off-by: Len Brown --- Reading git-diff-tree failed
