Subject: Re: [PATCH v1 1/2] scsi: ufs: Fix up clock scaling

Hi Can,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on scsi/for-next]
[also build test WARNING on v5.4-rc5 next-20191030]
[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]

url:    https://github.com/0day-ci/linux/commits/Can-Guo/UFS-driver-general-fixes-bundle-2/20191031-081324
base:   https://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.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
Reported-by: kbuild test robot <lkp@...el.com>


sparse warnings: (new ones prefixed by >>)

>> drivers/scsi/ufs/ufshcd.c:977:5: sparse: sparse: symbol 'ufshcd_scale_clks' was not declared. Should it be static?

Please review and possibly fold the followup patch.
