Failing to read the MTP over DSI should not bring down the
|
||
|
|
system and make us bail out from using the display, it turns
|
||
|
|
out that this happens when toggling the display off and on,
|
||
|
|
and that write is often still working so the display output
|
||
|
|
is just fine. Printing an error is enough.

|
Tested by killing the Gnome session repeatedly on the
|
||
|
|
Samsung Skomer.
