Subject: net: simplify net_client_parse() error management
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=21fccb2cbbacdc045f19605915e847de31ca9862;p=qemu.git

net: simplify net_client_parse() error management

All net_client_parse() callers exit in case of error.

Move exit(1) to net_client_parse() and remove error checking from
the callers.
