SubjectRe: [PATCH v2] watchdog: Compile possible drivers with COMPILE_TEST
Hi Luis,

[auto build test ERROR on v4.3-rc5 -- if it's inappropriate base, please suggest rules for selecting the more suitable base]

url: https://github.com/0day-ci/linux/commits/Luis-de-Bethencourt/watchdog-Compile-possible-drivers-with-COMPILE_TEST/20151015-025729
config: um-allmodconfig (attached as .config)
reproduce:
# save the attached .config to linux build tree
make ARCH=um
