patch "thermal: armada: Update Armada 380 thermal sensor coefficients" added to thermal-soc tree
Subsystems (3)
This is a simple automated notification to let you know that I've just added the patch titled
thermal: armada: Update Armada 380 thermal sensor coefficients
to my thermal-soc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git
in the fixes 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 patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.
All the best,
Eduardo Valentin
