This is a note to let you know that I've just added the patch titled
coresight: Potential uninitialized variable in probe()
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-next branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The "drvdata->atclk" clock is optional, but if it gets set to an error pointer then we're accidentally return an uninitialized variable instead of success.
