SubjectRe: [PATCH v5 03/14] spi: qup: Add completion timeout
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]

url: https://github.com/0day-ci/linux/commits/Varadarajan-Narayanan/spi-qup-Fixes-and-add-support-for-64k-transfers/20170725-033101
base: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next
config: arm64-defconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
reproduce:
wget https://raw.githubusercontent.com/01org/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=arm64

Note: the linux-review/Varadarajan-Narayanan/spi-qup-Fixes-and-add-support-for-64k-transfers/20170725-033101 HEAD 88e143f949247832b744d84f5163033eaba09abc builds fine.
It only hurts bisectibility.

All errors (new ones prefixed by >>):

>> drivers//spi/spi-qup.c:361:47: error: 'qup' undeclared (first use in this function)
if (rx_done && !wait_for_completion_timeout(&qup->done, timeout))
^~~
drivers//spi/spi-qup.c:361:47: note: each undeclared identifier is reported only once for each function it appears in

vim +/qup +361 drivers//spi/spi-qup.c
