SubjectRe: [PATCH 3/3] thermal: broadcom: Add Stingray thermal driver
Hi Pramod,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on soc-thermal/next]
[also build test WARNING on v4.17-rc7 next-20180529]
[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/Srinath-Mannam/Stingray-thermal-driver-support/20180529-145243
base: https://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git next
reproduce:
# apt-get install sparse
make ARCH=x86_64 allmodconfig
make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)
