[ Upstream commit 74c82dae6c474933f2be401976e1530b5f623221 ] We were accidentally initializing haptics->rated_voltage twice, and did not initialize overdrive voltage.

2018-02-28Input: twl6040-vibra - fix child-node lookupJohan Hovold
[ Upstream commit dcaf12a8b0bbdbfcfa2be8dff2c4948d9844b4ad ] Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at parent rather than just matching on its children. Later sanity checks on node properties (which would likely be missing) should prevent this from causing much trouble however, especially as the original premature free of the parent node has already been fixed separately (but that "fix" was apparently never backported to stable).

2018-02-28Input: twl6040-vibra - fix DT node memory managementH. Nikolaus Schaller
[ Upstream commit c52c545ead97fcc2f4f8ea38f1ae3c23211e09a8 ] commit e7ec014a47e4 ("Input: twl6040-vibra - update for device tree support") made the separate vibra DT node to a subnode of the twl6040. It now calls of_find_node_by_name() to locate the "vibra" subnode. This function has a side effect to call of_node_put on() for the twl6040 parent node passed in as a parameter. This causes trouble later on. Solution: we must call of_node_get() before of_find_node_by_name() Signed-off-by: H.

[ Upstream commit 5a8a6b89c15766446d845671d574a9243b6d8786 ] We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us.

2016-07-10Input: pmic8xxx-pwrkey - fix algorithm for converting trigger delayStephen Boyd
[ Upstream commit eda5ecc0a6b865561997e177c393f0b0136fe3b7 ] The trigger delay algorithm that converts from microseconds to the register value looks incorrect. According to most of the PMIC documentation, the equation is delay (Seconds) = (1 / 1024) * 2 ^ (x + 4) except for one case where the documentation looks to have a formatting issue and the equation looks like delay (Seconds) = (1 / 1024) * 2 x + 4 Most likely this driver was written with the improper documentation to begin with. According to the downstream sources the valid delays are from 2 seconds to 1/64 second, and the latter equation just doesn't make sense for that. Let's fix the algorithm and the range check to match the documentation and the downstream sources.

GNOME can already make use of the Windows key on multiple form factors, and other desktop environments can use it depending on the form factor.
