Subject: [PATCH 5.4 011/232] net: vxge: fix wrong __VA_ARGS__ usage
From: Zheng Wei <wei.zheng@...o.com>
[ Upstream commit b317538c47943f9903860d83cc0060409e12d2ff ]
printk in macro vxge_debug_ll uses __VA_ARGS__ without "##" prefix,
it causes a build error when there is no variable
arguments(e.g. only fmt is specified.).
