Subject: user: Restore debug usage message for '-d ?' in user mode emulation
X-Git-Tag: v0.15.1~16
X-Git-Url: https://git.proxmox.com/?p=qemu.git;a=commitdiff_plain;h=a80f53aee36f177203a2d4e7a046dc0365e42150

user: Restore debug usage message for '-d ?' in user mode emulation

The code which prints the debug usage message on '-d ?' for *-user
has to come before the check for "not enough arguments", so that
"qemu-foo -d ?" prints the list of possible debug log items rather than
the generic usage message. (This was inadvertently broken in commit
c235d73.)
