      USB: Disable hub-initiated LPM for comms devices. · e1f12eb6
      由 Sarah Sharp 提交于 
      Hub-initiated LPM is not good for USB communications devices.  Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.

If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data.  Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.

The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host.  In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.

Set the disable_hub_initiated_lpm flag for for all USB communications
drivers.  I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

      isdn: whitespace coding style cleanup · 475be4d8
      由 Joe Perches 提交于 
      isdn source code uses a not-current coding style.

Update the coding style used on a per-line basis
so that git diff -w shows only elided blank lines
at EOF.

Done with emacs and some scripts and some typing.

Built x86 allyesconfig.
No detected change in objdump -d or size.

      drivers/isdn: delete double assignment · 4101e976
      由 Julia Lawall 提交于 
      Delete successive assignments to the same location.  In the first case, the
hscx array has two elements, so change the assignment to initialize the
second one.  In the second case, the two assignments are simply identical.
Furthermore, neither is necessary, because the effect of the assignment is
only visible in the next line, in the assignment in the if test.  The patch
inlines the right hand side value in the latter assignment and pulls that
assignment out of the if test.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>

expression i;

*i = ...;
 i = ...;
