commit: 36c0f8b32c4bd4f668cedfba6d97afaa84f055fb [310/383] [media] vb2: replace void *alloc_ctxs by struct device *alloc_devs
config: arm-allmodconfig (attached as .config)
compiler: arm-linux-gnueabi-gcc (Debian 5.3.1-8) 5.3.1 20160205
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 36c0f8b32c4bd4f668cedfba6d97afaa84f055fb
# save the attached .config to linux build tree
make.cross ARCH=arm
Note: the linuxtv-media/master HEAD 9ad52b4db79d168867a2ca105eca00fb9cb28fe5 builds fine.
It only hurts bisectibility.
