SubjectRe: [PATCH v2 2/6] serial: imx: Simplify DMA disablement
Hi Nandor,

[auto build test ERROR on tty/tty-testing]
[also build test ERROR on v4.12 next-20170706]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base: tty-testing
config: arm-multi_v5_defconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 6.1.1-9) 6.1.1 20160705
wget -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=arm

Note: the linux-review/Romain-Perier/serial-imx-various-improvements/20170706-153226 HEAD c99e6e0fd195719d99b5ce9a4f9a155243772578 builds fine.
It only hurts bisectibility.

All errors (new ones prefixed by >>):

drivers/tty/serial/imx.c: In function 'imx_disable_dma':
>> drivers/tty/serial/imx.c:1250:2: error: 'temp' undeclared (first use in this function)
temp = readl(sport->port.membase + UCR2);
drivers/tty/serial/imx.c:1250:2: note: each undeclared identifier is reported only once for each function it appears in
