hwmon: (asus_atk0110) fix uninitialized data access
[ Upstream commit a2125d02443e9a4e68bcfd9f8004fa23239e8329 ]
The latest gcc-7 snapshot adds a warning to point out that when
atk_read_value_old or atk_read_value_new fails, we copy
uninitialized data into sensor->cached_value:
drivers/hwmon/asus_atk0110.c: In function 'atk_input_show':
drivers/hwmon/asus_atk0110.c:651:26: error: 'value' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Adding an error check avoids this. All versions of the driver
are affected.
Fixes: 2c03d07ad54d ("hwmon: Add Asus ATK0110 support")
