Hi Vandita, Thank you for the patch! Yet something to improve: [auto build test ERROR on drm-intel/for-linux-next] [cannot apply to v5.4-rc8 next-20191118] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Vandita-Kulkarni/Add-support-for-mipi-dsi-cmd-mode/20191120-015713 base: git://anongit.freedesktop.org/drm-intel for-linux-next config: i386-defconfig (attached as .config) compiler: gcc-7 (Debian 7.4.0-14) 7.4.0 reproduce: # save the attached .config to linux build tree make ARCH=i386 If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All error/warnings (new ones prefixed by >>): In file included from drivers/gpu/drm/i915/display/intel_display_types.h:46:0, from drivers/gpu/drm/i915/i915_irq.c:39: drivers/gpu/drm/i915/i915_irq.c: In function 'gen11_dsi_configure_te': >> drivers/gpu/drm/i915/i915_irq.c:2590:19: error: implicit declaration of function 'DSI_INTR_MASK_REG'; did you mean 'TSFS_INTR_MASK'?
