Allow the PID descriptor building function to create up to PID_AXES_MAX FFB-enabled axes. This will allow better effect handling and support for devices with more than two FFB axis.
Devices with only one axis, can be actually presented as such. --- dlls/winebus.sys/bus_sdl.c | 2 +- dlls/winebus.sys/bus_udev.c | 5 ++- dlls/winebus.sys/hid.c | 63 +++++++++++++++++++++++++++------ dlls/winebus.sys/unix_private.h | 2 +- 4 files changed, 58 insertions(+), 14 deletions(-)
