USB : serial : call handle_dcd_change
When the device receive a DCD status change, forward the signal to the

. libunwind to be configured with --enable-debug-frame.

On ARM the debug info is not present in the .eh_frame sections but

Use libunwind to load and parse the debug info.
Dependencies:

This patch implements the functions required for the perf registers API,
allowing the perf tool to interface kernel register dumps with libunwind
in order to provide userspace backtracing.

Hi,
I've been looking into a problem where BLK_TN_PROCESS events are not
delivered to all devices which are being traced. This results in process
name being (null) when trace for a single device is parsed.
The reason for this problem is that trace_note_tsk() is called only if

Hello,
I'm not sure that the way I implemented if a given timer is used as
clock_source or clock_event_device is robust. Does it need locking?
The reason to create a timer device for each timer instead of a single
device of all of

cat /sys/bus/iio/devices/*/name

in rc.local

Hi Lee,
That's what the datasheet for the board says. Perhaps it's that that's
incorrect? Annoyingly, instead of printing the device name on the
package, ST put some non-Googleable nonsense is there instead
(probably the serial number). Nevertheless, I'll revert the patch and
