Subject: Re: [PATCH] dma-mapping: move dma configuration to bus infrastructure

Hi Nipun,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[also build test WARNING on v4.16-rc5 next-20180313]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url:    https://github.com/0day-ci/linux/commits/Nipun-Gupta/dma-mapping-move-dma-configuration-to-bus-infrastructure/20180313-225250
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> drivers/base/platform.c:1133:5: sparse: symbol 'platform_dma_configure' was not declared. Should it be static?
>> drivers/base/platform.c:1149:6: sparse: symbol 'platform_dma_deconfigure' was not declared. Should it be static?

Please review and possibly fold the followup patch.
