Following the latest commit "RemotePlugin: added QSTR_TO_STDSTR macro and use it in LVSL/ZASF", lmms fails to build with the following error:

/xxxx/lmms/plugins/zynaddsubfx/zynaddsubfx.cpp: In member function ‘void zynAddSubFx::initRemotePlugin()’:
/xxxx/lmms/lmms/plugins/zynaddsubfx/zynaddsubfx.cpp:242: error: request for member ‘toUtf8’ in ‘"ZynAddSubFX"’, which is of non-class type ‘const char [12]’

Reverting to the previous revision allows lmms to be built.
