iio: accel: mma9551_core: Prevent uninitialized variable in mma9551_read_config_word()
[ Upstream commit 64a68158738ec8f520347144352f7a09bdb9e169 ]
Smatch Warns:
drivers/iio/accel/mma9551_core.c:299
mma9551_read_config_word() error: uninitialized symbol 'v'.
When (offset >= 1 << 12) is true mma9551_transfer() will return -EINVAL
without 'v' being initialized, so check for the error and return.
Note: No actual bug as caller checks the return value and does not
use the parameter in the problem case.
