Subject: [PATCH] zfsinfo: Correct a check for error allocating memory
|
|
|
|
|
|
|
|
|
|
While arguably the check for grub_errno is correct, we should really be
|
|
|
|
|
checking the return value from the function since it is always possible
|
|
|
|
|
that grub_errno was set elsewhere, making this code behave incorrectly.
|
|
|
|
|
|
|
|
|
|
Fixes: CID 73668
