Subject: [PATCH] I2C: Setting w83627hf fan divisor 128 fails.
X-Git-Tag: MMI-PSA29.97-13-9~56759^2~160^2~34
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=abc01922477104e8d72b494902aff37135c409e7;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

[PATCH] I2C: Setting w83627hf fan divisor 128 fails.

Jarkko Lavinen provided patch to fix: "couldn't set the divisor 128
through fan1_div sysfs entry even though the chip supports it and
setting divisors 1..64 worked. This was due to POWER_TO_REG() only
checking 2's powers 0 till 5 but not 6."

This patch applies that fix to w83627hf and w83781d drivers.
