Hi Green,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on linus/master]
[cannot apply to v5.4-rc2 next-20191011]
[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]

reproduce:
        # apt-get install sparse
        # sparse version: v0.6.1-rc1-43-g0ccb3b4-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 >>)

>> drivers/dma/sf-pdma/sf-pdma.c:100:6: sparse: sparse: symbol 'sf_pdma_disclaim_chan' was not declared. Should it be static?
>> drivers/dma/sf-pdma/sf-pdma.c:107:32: sparse: sparse: symbol 'sf_pdma_prep_dma_memcpy' was not declared. Should it be static?

Please review and possibly fold the followup patch.
