5.15-stable review patch. If anyone has any objections, please let me know.

From: Sven Eckelmann <sven@xxxxxxxxxxxxx>
[ Upstream commit 813e62a6fe7539fdf0d8e018d4f157b57bdaeedd ]
The commit 94dfc73e7cf4 ("treewide: uapi: Replace zero-length arrays with
flexible-array members") changed various structures from using 0-length
arrays to flexible arrays
net/batman-adv/bat_v_elp.c: note: in included file:
./include/linux/ethtool.h:148:38: warning: nested flexible array
net/batman-adv/bat_v_elp.c:128:9: warning: using sizeof on a flexible structure
In theory, this could be worked around by using {} as initializer for the
variable on the stack. But this variable doesn't has to be initialized at
all by the caller of __ethtool_get_link_ksettings - everything will be
initialized by the callee when no error occurs.
