The tc1100-wmi driver should print the current states of wireless LAN and jogdial brightness control when "cat /sys/devices/platform/tc1100-wmi/wireless" and "cat /sys/devices/platform/tc1100-wmi/jogdial" are executed, respectively. 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 <tweenk.pl@gmail.com> Acked-by: Carlos Corbacho <carlos@strangeworlds.co.uk> Signed-off-by: Len Brown <len.brown@intel.com> |
