Subject: [PATCH] platform/x86: thinkpad_acpi: Select INPUT_SPARSEKMAP in
 Kconfig

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

Now that drivers/platform/x86/thinkpad_acpi.c uses
sparse_keymap_report_event(), it must select INPUT_SPARSEKMAP in its
Kconfig option otherwise the build fails with:

  ld: vmlinux.o: in function `tpacpi_input_send_key':
  thinkpad_acpi.c:(.text+0xd4d27f): undefined reference to `sparse_keymap_report_event'
  ld: vmlinux.o: in function `hotkey_init':
  thinkpad_acpi.c:(.init.text+0x66cb6): undefined reference to `sparse_keymap_setup'

Fixes: 42f7b965de9d ("platform/x86: thinkpad_acpi: Switch to using sparse-keymap helpers")
