* misc: add missing __devexit_p() annotationsArnd Bergmann2012-04-181-1/+1
| | | | | | | | | | Drivers that refer to a __devexit function in an operations structure need to annotate that pointer with __devexit_p so it is replaced with a NULL pointer when the section gets discarded.

* TTY: remove re-assignments to tty_driver membersJiri Slaby2012-03-081-4/+1
| | | | | | | | | | | | | | All num, magic and owner are set by alloc_tty_driver. No need to re-set them on each allocation site. pti driver sets something different to what it passes to alloc_tty_driver. It is not a bug, since we don't use the lines parameter in any way. Anyway this is fixed, and now we do the right thing.

* drivers/misc/pti.c: give 'comm' function scope in ↵Jesper Juhl2011-09-141-7/+5
| | | | | | | | | | | | | | | | | | pti_control_frame_built_and_sent() In drivers/misc/pti.c::pti_control_frame_built_and_sent() we assign 'comm' to 'thread_name_p' if (!thread_name). The problem is that 'comm' then goes out of scope and later we use 'thread_name_p' which now refers to an out-of-scope variable. To fix that, simply move 'comm' up to have function scope.

| * PTI feature to allow user to name and mark masterchannel request.J Freyensee2011-07-011-39/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature addition provides a new parameter in pti_request_masterchannel() to allow the user to provide their own name to mark the request when the trace is viewed in a PTI SW trace viewer (like MPTA). If a name is not provided and NULL is provided, the 'current' process name is used. API function header documentation documents this.

* Intel PTI implementaiton of MIPI 1149.7.J Freyensee2011-05-131-0/+980
The PTI (Parallel Trace Interface) driver directs trace data routed from various parts in the system out through an Intel Penwell PTI port and out of the mobile device for analysis with a debugging tool (Lauterbach or Fido). Though n_tracesink and n_tracerouter line discipline drivers are used to extract modem tracing data to the PTI driver and other parts of an Intel mobile solution, the PTI driver can be used independent of n_tracesink and n_tracerouter. You should select this driver if the target kernel is meant for an Intel Atom (non-netbook) mobile device containing a MIPI P1149.7 standard implementation.
