[ Upstream commit 53aba458f23846112c0d44239580ff59bc5c36c3 ]
The hns3 driver define an array of string to show the coalesce
info, but if the kernel adds a new mode or a new state,
out-of-bounds access may occur when coalesce info is read via
debugfs, this patch fix the problem.
Fixes: c99fead7cb07 ("net: hns3: add debugfs support for interrupt coalesce")
