Hi Edward,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tegra/for-next]
[also build test ERROR on v4.18-rc6 next-20180727]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux.git for-next
config: arm-multi_v7_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        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

Note: the linux-review/Jorge-Sanjuan/ASoC-Tegra30-TDM-support/20180728-163720 HEAD 14bbc96df0fa027f7bc057eb2da8181baff4e22c builds fine.
      It only hurts bisectibility.
