Hi Stefan,
FYI, the error/warning still remains.
tree: https://kernel.googlesource.com/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git devel
head: f2ae04c45b1a9d6c61faa8a946d515f81876e703
commit: e38a9a437fb93ddafab5030165e4c6a3a5021669 [16/53] pinctrl: bcm2835: Add support for BCM2711 pull-up functionality
config: m68k-allmodconfig (attached as .config)
compiler: m68k-linux-gcc (GCC) 7.4.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout e38a9a437fb93ddafab5030165e4c6a3a5021669
# save the attached .config to linux build tree
GCC_VERSION=7.4.0 make.cross ARCH=m68k
