Input: twl4030-vibra - fix sibling-node lookup

2018-01-23T18:50:16Z

commit 5b189201993ab03001a398de731045bfea90c689 upstream. A helper purported to look up a child node based on its name was using the wrong of-helper and ended up prematurely freeing the parent of-node while searching the whole device tree depth-first starting at the parent node.

Input: twl6040-vibra - fix child-node lookup

2018-01-23T18:50:16Z

commit dcaf12a8b0bbdbfcfa2be8dff2c4948d9844b4ad upstream. 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).

Input: twl6040-vibra - fix DT node memory management

2018-01-23T18:50:15Z

commit c52c545ead97fcc2f4f8ea38f1ae3c23211e09a8 upstream. 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. Nikolaus Schaller Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: ims-psu - check if CDC union descriptor is sane

2017-11-18T10:11:05Z

commit ea04efee7635c9120d015dcdeeeb6988130cb67a upstream. Before trying to use CDC union descriptor, try to validate whether that it is sane by checking that intf->altsetting->extra is big enough and that descriptor bLength is not too big and not too small.

commit ac2ee9ba953afe88f7a673e1c0c839227b1d7891 upstream. Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer should a malicious device lack endpoints.

Input: drv260x - fix input device's parent assignment

2017-01-09T07:07:51Z

commit 5a8a6b89c15766446d845671d574a9243b6d8786 upstream. 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.

Input: uinput - handle compat ioctl for UI_SET_PHYS

2016-06-08T01:14:32Z

commit affa80bd97f7ca282d1faa91667b3ee9e4c590e6 upstream. When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS ioctl needs to be treated with special care, as it has the pointer size encoded in the command.

Input: pwm-beeper - fix - scheduling while atomic

2016-06-01T19:15:49Z

commit f49cf3b8b4c841457244c461c66186a719e13bcc upstream. Pwm config may sleep so defer it using a worker. On a Freescale i.MX53 based board we ran into "BUG: scheduling while atomic" because input_inject_event locks interrupts, but imx_pwm_config_v2 sleeps. Tested on Freescale i.MX53 SoC with 4.6.0.
