Subject: [PATCH] fallback: fix double free of dp
|
|
|
|
If the boot option recorded in csv is not in a media device path, the
|
|
corresponding full device path will be referred for creating the boot
|
|
variable.
|
|
|
|
However, the current code logic always frees the full device path
|
|
(full_device_path) and the media device path (dp) separately. In order
|
|
to resolve this issue, always check whether dp equals to full_device_path
|
|
before freeing dp.
