PM / Runtime: Add macro to test for runtime PM events

2011-08-19T21:49:48+00:00

This patch (as1482) adds a macro for testing whether or not a
pm_message value represents an autosuspend or autoresume (i.e., a
runtime PM) event.  Encapsulating this notion seems preferable to
open-coding the test all over the place.

usb: wwan: fix compilation without CONFIG_PM_RUNTIME

2011-03-23T20:16:06+00:00

The pm usage counter must be accessed with the proper wrappers
to allow compilation under all configurations.

tty: remove filp from the USB tty ioctls

2011-02-17T19:59:14+00:00

We don't use it so we can trim it from here as we try and stamp the file
object dependencies out of the serial code.

tiocmset: kill the file pointer argument

Doing tiocmget was such fun we should do tiocmset as well for the same

tiocmget: kill off the passing of the struct file

2011-02-17T19:47:33+00:00

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

usb_wwan: fix error case in close()

2011-02-17T18:51:13+00:00

The device never needs to be resumed in close(). But the counters
must be balanced. As resumption can fail, but the counters must
be balanced, use the _no_resume() version which cannot fail.

usb_wwan: error case of resume

2011-02-17T18:51:12+00:00

If an error happens during resumption.
The remaining data has to be cleanly discarded and the pm
counters have to be adjusted.

As soon as the first error happens, the write must
be stopped, lest we send mutilated messages.
