Input: matrix_keypad - fix race when disabling interrupts

2018-03-18T10:15:42+00:00

commit ea4f7bd2aca9f68470e9aac0fc9432fd180b1fe7 upstream. If matrix_keypad_stop() is executing and the keypad interrupt is triggered, disable_row_irqs() may be called by both matrix_keypad_interrupt() and matrix_keypad_stop() at the same time, causing interrupts to be disabled twice and the keypad being "stuck" after resuming. Take lock when setting keypad->stopped to ensure that ISR will not race with matrix_keypad_stop() disabling interrupts.

Input: do not emit unneeded EV_SYN when suspending

2018-02-07T19:07:53+00:00

commit 00159f19a5057cb779146afce1cceede692af346 upstream. Do not emit EV_SYN/SYN_REPORT on suspend if there were no keys that are still pressed as we are suspending the device (and in all other cases when input core is forcibly releasing keys via input_dev_release_keys() call).

Input: twl4030-vibra - fix sibling-node lookup

2018-01-31T13:46:12+00:00

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

2018-01-31T13:46:12+00:00

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

2018-01-31T13:46:12+00:00

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

[ Upstream commit a4c2a13129f7c5bcf81704c06851601593303fd5 ] TUXEDO BU1406 does not implement active multiplexing mode properly, and takes around 550 ms in i8042_set_mux_mode(). Given that the device does not have external AUX port, there is no downside in disabling the MUX mode.
