Input: sparse-keymap - use a managed allocation for keymap copy

2017-03-08T22:28:53+00:00

Some platform drivers use devm_input_allocate_device() together with sparse_keymap_setup() in their .probe callbacks. While using the former simplifies error handling, using the latter necessitates calling sparse_keymap_free() in the error path and upon module unloading to avoid leaking the copy of the keymap allocated by sparse_keymap_setup(). To help prevent such leaks and enable simpler error handling, make sparse_keymap_setup() use devm_kmemdup() to create the keymap copy so that it gets automatically freed. This works for both managed and non-managed input devices as the keymap is freed after the last reference to the input device is dropped. Note that actions previously taken by sparse_keymap_free(), i.e. taking the input device's mutex and zeroing its keycode and keycodemax fields, are now redundant because the managed keymap will always be freed after the input device is unregistered.

drivers/input: Add module.h to modular drivers implicitly using it

2011-10-31T23:31:16+00:00

A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in input dir are actually calling out for explicitly in advance. Signed-off-by: Paul Gortmaker
