From abc01922477104e8d72b494902aff37135c409e7 Mon Sep 17 00:00:00 2001 From: Grant Coady Date: Thu, 12 May 2005 13:41:51 +1000 Subject: [PATCH] [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.
