When the 'if' has the brackets, then the 'else' should have them as well, even if there is only a single line under 'else'. It's not strictly to this patch, but you can address that later somewhere (just saw it here). > - con &= ~(1 << EXYNOS_TMU_CORE_EN_SHIFT); > + con &= ~BIT(EXYNOS_TMU_CORE_EN_SHIFT); > > pd_det_en = on ?

For what it's worth, this issue disappears after the final patch of this series, because the other branch reduces to a single line too (all the interrupt_en operations are done in the tmu_set_*_temp functions). Thank you :) Mateusz

That sounds perfect. I'm planning to build&run the patch set today evening, so I will finish the review of the patch 9/9.

The original driver did not use that macro and it allows us to make our intentions slightly clearer. Signed-off-by: Mateusz Majewski <m.majewski2@samsung.com> --- drivers/thermal/samsung/exynos_tmu.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-)
