(1.8 branch) fix FTBS against recent xorg server tree
requested to merge metux/xf86-input-synaptics:submit/fix-BUG_RETURN_VAL-for-1.8 into synaptics-1.8-branch
Recent xserver master moved out the BUG_*() macros from os.h, causing FTBS on xf86-input-synaptics:
synaptics.c: In function 'clickpad_guess_clickfingers': synaptics.c:2638:5: error: implicit declaration of function 'BUG_RETURN_VAL' [-Werror=implicit-function-declaration] 2638 | BUG_RETURN_VAL(hw->num_mt_mask > sizeof(close_point) * 8, 0);
Since that macro is only used once, and that particular case deserves some more expressive error message anyways, it's trivial doing an explicit error printout here, instead of having to support the BUG_* macros as official module API on xserver side forever.
