the fields must be null-terminated:
  the caller may use it as null-terminted string, next.

Added Peter to cc on this one too, it's best that he queues
all the twl changes.

  is it suitable to sync the MAINTAINER file for it ?
    if suitable, can you help to change it ?

  thanks.

Yes I suggest we add Peter as the maintainer for all twl
related things.

I can create a branch for you in our gitorious tree
(git://gitorious.org/omap-audio/linux-audio.git) for this patch. But I think
for now it would be best if you could take this via linux-omap (the file is
under arch/arm/mach-omap2 anyways)

Regards,
Péter

OK thanks I'll apply with your ack to omap-for-v3.9/fixes-noncritical.

  Does it mean: we need not sync MAINTAINERS file for twl-*, recently ?

  :-)

  thanks.

  ok, thanks.

  if necessary (no other members do it), I should perform.
  if really should I do:

    requirements:
      A) I should succeed provide at least 3 valuable patches to twl-*
           (or I am not qualified to provide the sync MAINTAINERS patch)

      B) relative member need give strictly checking for the patch.
           (so can evaluate whether I have been qualified)

      C) it is necessary to be monitored by the relative mailing lists.

    I should try:
      A) need mainly focus on the omap2, specially for twl-*

      B) the patch type should be for bug fixing:
           (I am not familiar with omap2, so can not for new features)
          i. memory override.
         ii. resource management.
        iii. others (compiling issue, type cast, ...)

      C) should provide 3 twl-* valuable patches within 1 month.
           (have finished one: strlcpy, in Jan 30 2013)
           (so need finish the other 2 patches, before Feb 28 2013)

    hope I can succeed.

    welcome any members to provide suggestions and completions.


  thanks.
