From 499e830fad1c109f6c009d6ceb2256ced19e4452 Mon Sep 17 00:00:00 2001 From: Jens Rehsack Date: Thu, 18 Apr 2019 16:08:42 +0200 Subject: kernel-module-split.bbclass: support CONFIG_MODULE_COMPRESS=y In case, kernel config enables compressed modules, support of splitting via split_kernel_module_packages won't find any module. So, first expand module pattern regex to recognize compressed modules and then objcopy on temporary extacted to extract module information.
