ACPI / fan: avoid null pointer deference error Fix a null pointer deference by acpi_driver_data() if device is null. We should only set cdev and check this is OK after we are sure device is not null. Smatch analysis: drivers/acpi/fan.c:179 acpi_fan_remove() warn: variable dereferenced before check 'device' (see line 177) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Rafael J.
