Subject: hw/char/exynos4210_uart: Implement post_load function
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c9d3396d80fe7ece9bcc7a688be6f98e4988f0cf;p=qemu.git

hw/char/exynos4210_uart: Implement post_load function

After restoring a VM, serial parameters need to be updated to reflect
restored register values. Implement a post_load function to handle this
situation.
