Staging: bcm: Add min/max restrictions for IOCTL_BCM_REGISTER_READ_PRIVATE

This patch fixes two issues within bcm/Bcmchar.c. The
first condition in the or statement checks if variable
IoBuffer.OutputLength, defined from user space, is
greater than the maximum value allowed for an
unsigned short. IoBuffer.OutputLength is then used
in a kmalloc call to return a pointer to memory. If
this size is greater than an unsigned short, it
becomes useless. The second condition in the or statement
checks if the same variable, IoBuffer.OutputLength is
equal to zero before invoking the kmalloc call. In
this case, if a zero size is sent to kmalloc, a valid
pointer to memory is returned instead of the expected NULL.

staging: quatech_usb2: Potential lost wakeup scenario in TIOCMIWAIT

If the usermode app does an ioctl over this serial device  by
using TIOCMIWAIT, then the code will wait by setting the current
task state to TASK_INTERRUPTIBLE and then calling schedule().
This will be woken up by the qt2_process_modem_status on URB
completion when the port_extra->shadowMSR is set to the new
modem status.

However, this could result in a lost wakeup scenario due to a race
in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion
for new modem status in qt2_process_modem_status.
Due to this, the usermode app's task will continue to sleep despite a
change in the modem status.
