Subject: Re: [PATCH v2] clk: add devm_of_clk_get() and
 devm_of_clk_get_by_name() functions

Hi Paul,

[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]

config: arm-sa1100 (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 4b38631724b90dc5a717a4467cbf9377e3bf9af2
  # save the attached .config to linux build tree
  make.cross ARCH=arm
