buildroot/package/config/patches/15-use-PATH_MAX-for-path-buffer.patch

From 1408b15b98635a13bad2e2a50b3c2ae2ccdf625b Mon Sep 17 00:00:00 2001

Subject: [PATCH] kconfig: Use PATH_MAX instead of 128 for path buffer sizes.

This prevents the buffers being overflowed when using a config
file with a long name. PATH_MAX is used elsewhere in the same
file, so use it here as well.
