Hi Srinivas,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on abelloni/rtc-next]
[also build test ERROR on next-20200224]
[cannot apply to v5.6-rc3]
[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/abelloni/linux.git rtc-next
config: c6x-randconfig-a001-20200225 (attached as .config)
compiler: c6x-elf-gcc (GCC) 7.5.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
