[lm-sensors] [PATCH v3 05/25] hwmon: (it87) Don't use pdev as static driver variable

[lm-sensors] [PATCH v3 05/25] hwmon: (it87) Don't use pdev as static driver variable

[Guenter Roeck]

From: Guenter Roeck <linux@roeck-us.net>

Using the same varible name for function names and as static
variable invites misuse and prevents us from adding support
for a second chip. Rename pdev to it87_pdev and limit its use
to where it is needed.
