commit: 1624300f08d19703c8b2df299f55095db74cc2cd [13549/13557] genalloc: rename dev_get_gen_pool() to gen_pool_get()
config: arm-allyesconfig (attached as .config)
reproduce:
  wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
  chmod +x ~/bin/make.cross
  git checkout 1624300f08d19703c8b2df299f55095db74cc2cd
  # save the attached .config to linux build tree
  make.cross ARCH=arm
