[meta-freescale] [meta-fsl-arm][PATCH] fsl-vivante-kernel-driver-handler.bbclass: Fix kernel config when graphics kernel module config is changed

[Tom Hochstein]

Hi Otavio,

By 'in source defconfig', do you mean one in the recipe, as is done for linux-fslc? The fix does in fact already work for this case. I was actually working with linux-fslc when I discovered the bug.

Also, since kernel.bbclass processes the .config in do_configure, don't we have to use _prepend?

KERNEL_CONFIG_COMMAND ?= "oe_runmake_call -C ${S} O=${B} oldnoconfig || yes '' | oe_runmake -C ${S} O=${B} oldconfig"
kernel_do_configure() {
	...
	eval ${KERNEL_CONFIG_COMMAND}
}

Tom

I agree it can be simplified, but the prepend use here is what we ought to change. We should use _append so if someone uses the in source defconfig it will also work.
