stable inclusion from stable-5.10.77 commit be98be1a17e9502321889b2142b5cba4aec7e087 bugzilla: 185677 https://gitee.com/openeuler/kernel/issues/I4IAP7
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 4a089e95b4d6bb625044d47aed0c442a8f7bd093 upstream.
nios2:allmodconfig builds fail with
make[1]: *** No rule to make target 'arch/nios2/boot/dts/""', needed by 'arch/nios2/boot/dts/built-in.a'. Stop. make: [Makefile:1868: arch/nios2/boot/dts] Error 2 (ignored)
This is seen with compile tests since those enable NIOS2_DTB_SOURCE_BOOL, which in turn enables NIOS2_DTB_SOURCE. This causes the build error because the default value for NIOS2_DTB_SOURCE is an empty string. Disable NIOS2_DTB_SOURCE_BOOL for compile tests to avoid the error.
