[PATCH 3/5] drm/msm/adreno: Load the firmware before bringing up the hardware

[kbuild test robot]

Hi Jordan,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on robclark/msm-next]
[also build test ERROR on v4.17 next-20180608]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

base:   git://people.freedesktop.org/~robclark/linux msm-next
config: arm64-defconfig (attached as .config)
compiler: aarch64-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        GCC_VERSION=7.2.0 make.cross ARCH=arm64 

Note: the linux-review/Jordan-Crouse/drm-msm-Add-support-for-Adreno-a6xx/20180612-022828 HEAD 716a0bd2934f1b01e622ac7a6714789861824f8f builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
