This patch extends the of-thermal.c to provide check if trip point is enabled.
Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> --- Changes for v2: - Replace int with bool - Replace 1/0 with true/false - Add check if data pointer is not NULL - Add missing doxygen style comment for the function --- drivers/thermal/of-thermal.c | 20 ++++++++++++++++++++ drivers/thermal/thermal_core.h | 5 +++++ 2 files changed, 25 insertions(+)
