Module: wine Branch: master Commit: 8d052561724f9c8d9e7770964bfaebdd01e98e60 URL: https://source.winehq.org/git/wine.git/?a=commit;h=8d052561724f9c8d9e7770964...

dinput: Cap the buffer size to 20.
When a program calls SetProperty with DIPROP_BUFFERSIZE, dinput records this value for GetProperty but only uses it when the device can support that number of buffers otherwise a max value.
