 use case

Hi Cheng-Yi,

I love your patch! Perhaps something to improve:

[auto build test WARNING on rockchip/for-next]
[also build test WARNING on v5.4-rc5 next-20191028]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git for-next
reproduce:
        # apt-get install sparse
        # sparse version: v0.6.1-dirty
        make ARCH=x86_64 allmodconfig
        make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag

sparse warnings: (new ones prefixed by >>)

>> sound/soc/rockchip/rockchip_max98090.c:475:23: sparse: sparse: symbol 'rk_card_configs' was not declared. Should it be static?

Please review and possibly fold the followup patch.
