Since we do not have interrupts on BCM7216, we cannot have trip point crossing, the thermal subsystem expects us to provide a NULL set_trips operation in that case, so make it possible to provide per-process thermal_zone_of_device_ops Reviewed-by: Amit Kucheria <redacted> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> --- drivers/thermal/broadcom/brcmstb_thermal.c | 15 ++++++++++++--- 1 file changed, 12 insertions(+), 3 deletions(-)
