chardev: Use QEMUChrEvent enum in IOEventHandler typedef
The Chardev events are listed in the QEMUChrEvent enum. By using the enum in the IOEventHandler typedef we: - make the IOEventHandler type more explicit (this handler process out-of-band information, while the IOReadHandler is in-band), - help static code analyzers. This patch was produced with the following spatch script: @match@ expression backend, opaque, context, set_open; identifier fd_can_read, fd_read, fd_event, be_change; @@ qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event, be_change, opaque, context, set_open); @depends on match@ identifier opaque, event; identifier match.fd_event; @@ static -void fd_event(void *opaque, int event) +void fd_event(void *opaque, QEMUChrEvent event) { ... } Then the typedef was modified manually in include/chardev/char-fe.h.
