mfd: fix undefined twl4030-power resconfig value checks
The code tries to skip values initialized with -1, but since the values are unsigned the comparison is always true. The patch eliminates the following compiler warnings: drivers/mfd/twl4030-power.c: In function 'twl4030_configure_resource': drivers/mfd/twl4030-power.c:338: warning: comparison is always true due to limited range of data type drivers/mfd/twl4030-power.c:358: warning: comparison is always true due to limited range of data type drivers/mfd/twl4030-power.c:363: warning: comparison is always true due to limited range of data type Signed-off-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
