From c2a6210883ae6b9b1e2d64433105b6cb1b1adffb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Abonnel?= Date: Sun, 14 Jan 2024 07:26:20 +0000 Subject: [PATCH] Restrict Kernel Version Check to Below 6.1.39 modifies the kernel version check in the source code to ensure compatibility with kernel versions below 6.1.39. The change was necessary due to the removal of the REGULATORY_IGNORE_STALE_KICKOFF flag in recent kernel versions, which caused compilation issues. The modified check now correctly excludes kernel versions 6.1.39 and above, preventing these issues.
