patch "thermal: exynos: Disable the regulator on probe failure" added to thermal-soc tree

This is a simple automated notification to let you know that I've just added the patch titled

thermal: exynos: Disable the regulator on probe failure

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

Subject: thermal: exynos: Disable the regulator on probe failure

During probe the regulator (if present) was enabled but not disabled in case of failure. So an unsuccessful probe lead to enabling the regulator which was actually not needed because the device was not enabled.

Additionally each deferred probe lead to increase of regulator enable count so it would not be effectively disabled during removal of the device.

Test HW: Exynos4412 - Trats2 board
