meta-agl-bsp: Add CONFIG_LSM workaround for 5.1+ kernels
Add explicit clearing of CONFIG_LSM before running "make oldconfig" in the do_configure_append added by linux-agl.inc. This ensures that the derived value of CONFIG_LSM will reflect configuration changes done by the merged AGL provided fragments, i.e. SMACK being enabled. Without it, kernel recipes that are not based on linux-yocto.bbclass or have their own fragment handling done via prepend will end up with an incorrect value of CONFIG_LSM which effectively disables SMACK. Examples include the linux-imx or linux-fslc kernels used by NXP. Bug-AGL: SPEC-2932 Change-Id: Id99906e3de75128ebc54866d43d89d3a24bb1cf2 Signed-off-by: Scott Murray <scott.murray@konsulko.com>
