Temporarily change CONFIG_HID_HAPTIC to be bool instead of tristate, until we implement a permanent solution. --- Recently the CONFIG_HID_HAPTIC Kconfig option was reported as causing the following build errors: MODPOST Module.symvers ERROR: modpost: "hid_haptic_init" [drivers/hid/hid-multitouch.ko] undefined! ERROR: modpost: "hid_haptic_pressure_increase" [drivers/hid/hid-multitouch.ko] undefined! ERROR: modpost: "hid_haptic_check_pressure_unit" [drivers/hid/hid-multitouch.ko] undefined!

ERROR: modpost: "hid_haptic_pressure_reset" [drivers/hid/hid-multitouch.ko] undefined! make[3]: *** [/home/thl/var/linux.dev/scripts/Makefile.modpost:147: Module.symvers] Error 1 when the kernel is compiled with the following configuration: CONFIG_HID=y CONFIG_HID_MULTITOUCH=m CONFIG_HID_HAPTIC=m To resolve this, temporarily change the CONFIG_HID_HAPTIC option to be bool, until we arrive at a permanent solution to enable CONFIG_HID_HAPTIC to be tristate.
