commit: 3b4ad5b46d631c04726e3b7533b2360fa4a8b24f [52/52] bus: fsl-mc: add custom .dma_configure implementation
config: i386-randconfig-a003-20210705 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-22) 9.3.0
reproduce (this is a W=1 build):
        git remote add linux-arm git://git.armlinux.org.uk/~rmk/linux-arm
        git fetch --no-tags linux-arm cex7
        git checkout 3b4ad5b46d631c04726e3b7533b2360fa4a8b24f
        # save the attached .config to linux build tree
        mkdir build_dir
        make W=1 O=build_dir ARCH=i386 SHELL=/bin/bash
