Subject: Re: [PATCHv2] thermal: exynos: Add support for TRIM_RELOAD feature at
Exynos3250
Dear Eduardo,
I'm so sorry. This patch has build break as following:
It is my mistake about missing 'or' operation when adding TMU_SUPPORT_TRIM_RELOAD.
+ .features = (TMU_SUPPORT_EMULATION | TMU_SUPPORT_TRIM_RELOAD\
I'll send new patch to fix it right now.
Best Regards,
Chanwoo Choi
