TTY: remove re-assignments to tty_driver members

2012-03-08T19:37:58+00:00

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.

TTY: remove minor_num from tty_driver

2012-03-08T19:30:21+00:00

It was added back in 2004 and never used for anything real. Remove the
only assignment in the tree as well.

TTY: use tty_standard_install

2012-02-02T23:09:47+00:00

Use the helper in the rest of the tty drivers. This is a simple
replacement.

drivers/misc/pti.c: give 'comm' function scope in pti_control_frame_built_and_sent()

2011-09-15T01:09:38+00:00

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.

2011-07-01T22:39:38+00:00

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.
