Hi Linus,
I love your patch! Yet something to improve:
[auto build test ERROR on staging/staging-testing]
url: https://github.com/0day-ci/linux/commits/Linus-Walleij/staging-wfx-Get-descriptors-for-GPIOs/20200628-165448
base: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git 5bfb7eadc5874a3a08dd173d66a16a1ed0548444
config: sh-allyesconfig (attached as .config)
compiler: sh4-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
