e8df1674d3 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.

e228b7426e Staging: bcm: Add size maximum size restrictions for IOCTL_IDLE_REQ 
In the first alteration, the MAX_CNTL_PKT_SIZE is the
maximum size of the control packet in ->Adapter->txctlpacket[]
which is defined in InitAdapter(). This caps the size of
kmalloc memory allocation. In the second change, this max
cap fixes a potential memory corruption bug when subsequent
memset and memcpy calls are invoked.

5ac5bd8754 Staging: bcm: Add size minimum size restrictions for IOCTL_IDLE_REQ 
If IoBuffer.InputLength is zero then this will cause an Oops when
we dereference the ZERO_SIZE_PTR.  Or if it's smaller than
sizeof(struct link_request) then we would get memory corruption
when we set ->PLength in CopyBufferToControlPacket().

Revert changes in definitions that were submitted on May 11 2011 and
committed on June 7 2011. No reason for the change in these values was
given in the patch comment, it broke compatibility with older
versions, and was difficult to detect by the simultaneous move of the
lines of code.
