Subject: io: Add missing GCC_FMT_ATTR (fix -Werror=suggest-attribute=format)
X-Git-Tag: v2.11.0-rc0~46^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=52aa5644e8e89ebfc3b1d0abdb7cc502ce9db599;p=thirdparty%2Fqemu.git

io: Add missing GCC_FMT_ATTR (fix -Werror=suggest-attribute=format)

This fixes a compiler warning:

/qemu/io/channel-websock.c:163:5: error:
 function might be possible candidate for ‘gnu_printf’ format attribute
 [-Werror=suggest-attribute=format]
