Subject: ARM: tegra: acer-a500: Reduce thermal throttling hysteresis to 0.2C
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ecd021396efa2fda66d546c406d21b1ce6832206;p=linux.git

ARM: tegra: acer-a500: Reduce thermal throttling hysteresis to 0.2C

The 2C hysteresis is a bit too high, although CPU never gets hot on A500.
Nevertheless, let's reduce thermal throttling hysteresis to 0.2C, which is
a much more reasonable value.
