[lm-sensors] [PATCH] hwmon: Fix regression caused by typo in lm90.c

[Mark M. Hoffman]

From: Guillaume Chazarain <guichaz@yahoo.fr>

The commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h2c82a934759b2c9939c9e25865c2d7d1204b9e8
broke lm90 for my (Asus V6VA) laptop.

Before 2.6.23-rc1 and with the following patch, I get:

[g ~]$ sensors
max6657-i2c-0-4c
Adapter: SMBus I801 adapter at 0400
M/B Temp:    +64°C  (low  =    +0°C, high =  +127°C)
CPU Temp:  +78.9°C  (low  = +73.2°C, high = +88.2°C)
M/B Crit:   +105°C  (hyst =   +95°C)
CPU Crit:   +105°C  (hyst =   +95°C)

Which regressed into:

[g ~]$ sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
zsh: 2701 exit 1     sensors

and dmesg contains:

i2c-adapter i2c-0: Unsupported chip (man_id=0x4D, chip_id=0x4D).

It seems to be a typo, as address 0X4F is mentionned nowhere else in the file,
and my chip is actually at 0x4C.
