[Qemu-devel] [PATCH 4/4] chardev: remove context in chr_update_read_handler

[Peter Xu]

We had a per-chardev cache for context, then we don't need this
parameter to be passed in every time when chr_update_read_handler()
called.  As long as we are calling chr_update_read_handler() using
qemu_chr_be_update_read_handlers() we'll be fine.
