linux-stable.git/drivers, branch v4.1.6 Linux kernel stable tree thermal: exynos: Disable the regulator on probe failure 2015-08-17T03:52:25+00:00 Krzysztof Kozlowski k.kozlowski@samsung.com 2015-06-08T01:35:49+00:00 00d707ae64f062c2c4b488c76306278a1298557a commit 5f09a5cbd14ae16e93866040fa44d930ff885650 upstream. 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.

commit 5f09a5cbd14ae16e93866040fa44d930ff885650 upstream.

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.

Input: alps - only Dell laptops have separate button bits for v2 dualpoint sticks 2015-08-17T03:52:25+00:00 Hans de Goede hdegoede@redhat.com 2015-08-03T21:06:24+00:00 1770acb5356360a373c58835a8d1e786506a3f76 commit 073e570d7c2caae9910a993d56f340be4548a4a8 upstream. It turns out that only Dell laptops have the separate button bits for v2 dualpoint sticks and that commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has separate stick button bits") causes regressions on Toshiba laptops. This commit adds a check for Dell laptops to the code for handling these extra button bits, fixing this regression. This patch has been tested on a Dell Latitude D620 to make sure that it does not reintroduce the original problem.
