ACPI / EC: Remove unused functions and add prototype declaration in internal.h
Adds the prototype declarations of functions acpi_ec_add_query_handler() and acpi_ec_remove_query_handler() in header file internal.h and removes unused functions ec_burst_enable() and ec_burst_disable() in ec.c. This eliminates the following warnings in ec.c: drivers/acpi/ec.c:393:5: warning: no previous prototype for ‘ec_burst_enable’ [-Wmissing-prototypes] drivers/acpi/ec.c:402:5: warning: no previous prototype for ‘ec_burst_disable’ [-Wmissing-prototypes] drivers/acpi/ec.c:531:5: warning: no previous prototype for ‘acpi_ec_add_query_handler’ [-Wmissing-prototypes] drivers/acpi/ec.c:552:6: warning: no previous prototype for ‘acpi_ec_remove_query_handler’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Rafael J.
