      bas_gigaset: fix pre_reset handling · c6fdd8e5
      Tilman Schmidt authored
      The delayed work function int_in_work() may call usb_reset_device()
      and thus, indirectly, the driver's pre_reset method. Trying to
      cancel the work synchronously in that situation would deadlock.
      Fix by avoiding cancel_work_sync() in the pre_reset method.
      If the reset was NOT initiated by int_in_work() this might cause
      int_in_work() to run after the post_reset method, with urb_int_in
      already resubmitted, so handle that case gracefully.

      USB: Disable hub-initiated LPM for comms devices. · e1f12eb6
      Sarah Sharp authored
      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
      Joe Perches authored
      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/gigaset: tasklet_init - Remove unnecessary leading & from second arg · 5452fee2
      Joe Perches authored
      Changed function pointer use from non-majority address-of style
      to majority short form without & via:
      grep -rPl "\btasklet_init\s*\([^,\)]+,\s*\&" drivers/isdn | while read file ; do \
              perl -i -e 'local $/; while (<>) { s@(\btasklet_init\s*\([^,\)]+,\s*)\&@\1@g ; print ; }' $file ;\
      Compile tested allyesconfig x86
