Subject: [PATCH] port-serial: un-schedule flash operation as soon as it's
|
||||
cancelled
|
||||
|
||||
When a flash operation is started, it is always scheduled in an idle.
|
||||
If this operation is cancelled, we should right away un-schedule it,
|
||||
otherwise we may end up calling flash_do() with the GTask in the
|
||||
private info already gone.
|
||||
|
||||
