hwmon: (w83795) More style cleanups
Cleanups suggested by Guenter Roeck, falling into 4 categories: * Swapping test orders, because if (var == CONSTANT) is much easier to read than if (CONSTANT == var). * Simplifying comparisons with 0. * Dropping unneeded masks. * Dropping unneeded parentheses and curly braces. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>
