Input: elantech - make arrays debounce_packet static, reduces object code size

2017-09-11T21:23:40+00:00

Don't populate the arrays debounce_packet on the stack, instead make them static. Makes the object code smaller by over 870 bytes: Before: text data bss dec hex filename 30553 9152 0 39705 9b19 drivers/input/mouse/elantech.o After: text data bss dec hex filename 29521 9312 0 38833 97b1 drivers/input/mouse/elantech.o Signed-off-by: Colin Ian King Signed-off-by: Dmitry Torokhov

Merge branch 'bind_unbind' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core into next

2017-07-24T23:51:18+00:00

This brings in devm_device_add_group() and friends so that we can create driver-specific device attributes as managed resources.

Input: elantech - constify attribute_group structures

2017-07-12T21:19:28+00:00

attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by work with const attribute_group. So mark the non-const structs as const.

Merge tag 'v4.12-rc3' into next

2017-05-30T02:54:21+00:00

Sync with mainline to bring in changes in platform drovers dropping calls to sparse_keymap_free() so that we can remove it for good.

Input: elantech - force relative mode on a certain module

2017-05-12T01:00:32+00:00

One of Elan modules with sample version is 0x74 and hw_version is 0x03 has a bug in absolute mode implementation, so let it run in default PS/2 relative mode. Signed-off-by: KT Liao Signed-off-by: Dmitry Torokhov
