Subject: [PATCH] mei: hbm: drop BUG() from the hbm handler
|
|
|
|
Drop BUG() from the hbm handler in order not to crash the whole
|
|
kernel on faulty firmware implementation. Instead of it, just return
|
|
an error resulting into link reset.
|
|
There is no any known issue of faulty firmware in this matter,
|
|
the change is just to ease the development.
