From: Colin Ian King <colin.k...@canonical.com>
The masking operation on status is using a bitwise 'or' rather than
a bitwise 'and' operator, and hence the result is always non-zero
which is probably not what is intended. Fix this by using the correct
operator.
Detected by CoverityScan, CID#1475523 ("Wrong operator used")
