Let's introduce a common library file for the physmap show function duplicated between three different keyboard drivers. This largely copies the code from cros_ec_keyb.c which has the most recent version of the show function, while using the vivaldi_data struct from the hid-vivaldi driver. This saves a small amount of space in an allyesconfig build. $ ./scripts/bloat-o-meter vmlinux.before vmlinux.after add/remove: 3/0 grow/shrink: 2/3 up/down: 412/-720 (-308) Function old new delta vivaldi_function_row_physmap_show - 292 +292 _sub_I_65535_1 1057564 1057616 +52 _sub_D_65535_0 1057564 1057616 +52 e843419@49f2_00062737_9b04 - 8 +8 e843419@20f6_0002a34d_35bc - 8 +8 atkbd_parse_fwnode_data 480 472 -8 atkbd_do_show_function_row_physmap 316 76 -240 function_row_physmap_show 620 148 -472 Total: Before=285581925, After=285581617, chg -0.00% Signed-off-by: Stephen Boyd <swboyd@chromium.org> Tested-by: Stephen Boyd <swboyd@chromium.org> # coachz, wormdingler Link: https://lore.kernel.org/r/20220228075446.466016-3-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
