Subject: [PATCH 06/32] kern/file: Do not leak device_name on error in
|
|
grub_file_open()
|
|
|
|
If we have an error in grub_file_open() before we free device_name, we
|
|
will leak it.
|
|
|
|
Free device_name in the error path and null out the pointer in the good
|
|
path once we free it there.
