Hi Varadarajan,

[auto build test ERROR on spi/for-next]
[also build test ERROR on v4.13-rc2 next-20170726]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base:   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next

      It only hurts bisectibility.
