Subjectdrivers/media/pci/solo6x10/solo6x10-gpio.c:165: warning: unused variable 'ret'
tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: cd4175b11685b11c40e31a03e05084cc212b0649
commit: d3202d1981dc5a5f03f9afc96480619b48b60124 media: solo6x10: export hardware GPIO pins 8:31 to gpiolib interface
date: 7 weeks ago
config: x86_64-randconfig-a0-09241049 (attached as .config)
compiler: gcc-4.4 (Debian 4.4.7-8) 4.4.7
reproduce:
git checkout d3202d1981dc5a5f03f9afc96480619b48b60124
# save the attached .config to linux build tree
make ARCH=x86_64
