Hello

There is a bug in sermouse driver that inputattach program terminates
during suspend (or resume) to ram hence mouse does not work afer
resume. When i execute inputattach after resume, the mouse is
working.


strace from inputattach:

> ...
> select(4, [3], NULL, NULL, {0, 100000}) = 1 (in [3], left {0, 93000})
> read(3, "\t", 1)                        = 1
> select(4, [3], NULL, NULL, {0, 100000}) = 0 (Timeout)
> ioctl(3, TIOCSETD, [2])                 = 0
> ioctl(3, SPIOCSTYPE or VTXIOCGETINFO, 0xbfb28c84) = 0
> read(3, NULL, 0)                        = 0
> ^^^^^^ here it is blocked before i start STR
> 
> ioctl(3, TIOCSETD, [0])                 = 0
> close(3)                                = 0
> exit_group(0)                           = ?


inputattach is just sleeping on last read(), which is not supposed
to return, but it returns during STR.
