-tip testing has triggered this bug too, see the fix below.

Subject: [PATCH] eepc-wmi.c: Fix build error

-tip testing found:

eeepc-wmi.c:(.text+0x36673c): undefined reference to `sparse_keymap_report_event'
drivers/built-in.o: In function `eeepc_wmi_init':
eeepc-wmi.c:(.init.text+0x19cd0): undefined reference to `sparse_keymap_setup'
eeepc-wmi.c:(.init.text+0x19cf0): undefined reference to `sparse_keymap_free'
eeepc-wmi.c:(.init.text+0x19d0b): undefined reference to `sparse_keymap_free'
drivers/built-in.o: In function `eeepc_wmi_exit':
eeepc-wmi.c:(.exit.text+0x2e87): undefined reference to `sparse_keymap_free'

To fix this select INPUT_SPARSEKMAP, like the ASUS driver does.
