Hi all,

After merging the hwmon-staging tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/hwmon/lm90.c: In function 'lm90_write_convrate':
drivers/hwmon/lm90.c:597:42: warning: 'config_stop' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (data->flags & LM90_PAUSE_FOR_CONFIG && config_orig != config_stop)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/hwmon/lm90.c:598:3: warning: 'config_orig' may be used uninitialized in this function [-Wmaybe-uninitialized]
i2c_smbus_write_byte_data(client, LM90_REG_W_CONFIG1,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
config_orig);
~~~~~~~~~~~~

Introduced by commit
