Patch to fix issue
If you use BR2_LINUX_KERNEL_SOURCE_DIR and/or
BR2_LINUX_KERNEL_CUSTOM_GIT_VERSION along with BR2_LINUX_KERNEL_INTREE_DTS_NAME
the kernel will fail to build.
1. BR2_LINUX_KERNEL_SOURCE_DIR is not properly added when LINUX_BUILD_DTB is
defined so the make command fails.
2. BR2_LINUX_KERNEL_CUSTOM_GIT_VERSION and BR2_LINUX_KERNEL_SOURCE_DIR are
quoted strings and the "wildcard" call can't handle if a double-quote is
contained within it (which happens if BR2_LINUX_KERNEL_INTREE_DTS_NAME or
BR2_LINUX_KERNEL_CUSTOM_GIT_VERSION are defined). So if you are using a kernel
newer than 3.8, it will fail the new test and look for the dtb without the dts/
sub-directory.
linux/linux.mk:
$(KERNEL_ARCH_PATH)/boot/$(if $(wildcard \
$(addprefix
$(KERNEL_ARCH_PATH)/boot/dts/,$(KERNEL_DTBS))),dts/),$(KERNEL_DTBS)) \
$(BINARIES_DIR)/
The attached patch fixes both issues.
