Subject: [PATCH] launch/policy: fix at_console range assertion again
|
|
|
|
The previous fix did not actually consider that a full range can span up
|
|
until (uint32_t)-1. Fix this properly now, and just check manually for
|
|
an empty range before checking that the highest entry in the range can
|
|
be represented.
