Subject: [PATCH] zink: initialize drm_fd to -1
|
||
|
|

The `zink_internal_create_screen()` function initializes
|
||
|
|
`screen->drm_fd` to 0, a valid file descriptor value, via `rzalloc`.
|
||
|
|
|
||
|
|
If an error is found during initialization, the `zink_destroy_screen()`
|
||
|
|
function is invoked in the `fail` label and the `screen->drm_fd` is
|
||
|
|
closed because its value is 0 and `screen->drm_fd != -1` is checked.
|
||
|
|
|
||
|
|
Initialize `screen->drm_fd` to -1 to avoid this issue.
|
||
