Comment (by pulkomandy):
The driver cannot do much about this.
The idea of this is that an application should reply immediately to
signals (for example when you press control + C). So, if it is blocked in
a system call (such as read() or write()), that will be interrupted and
return EINTR to signal it to the application.
The application can then handle the signal, and restart its system call.
Alternatively, you can set SA_RESTART on the signal settings to let the
syscall be retried automatically.
