      drm/msm: add stubs for msm_{perf,rd}_debugfs_cleanup · 3a270e4d
      Arnd Bergmann authored
      We now call those two functions even when they are not defined
      or declared anywhere because DEBUG_FS is disabled:
      
      drivers/gpu/drm/msm/msm_drv.c: In function 'msm_drm_uninit':
      drivers/gpu/drm/msm/msm_drv.c:244:2: error: implicit declaration of function 'msm_perf_debugfs_cleanup';did you mean 'msm_framebuffer_cleanup'? [-Werror=implicit-function-declaration]
      drivers/gpu/drm/msm/msm_drv.c:245:2: error: implicit declaration of function 'msm_rd_debugfs_cleanup';did you mean 'msm_framebuffer_cleanup'? [-Werror=implicit-function-declaration]
      
      This adds empty stub implementations for that case.

      drm: bochs: Don't remove uninitialized fbdev framebuffer · 4fa13dbe
      Gabriel Krisman Bertazi authored
      In the same spirit of the fix for QXL in commit 86107838 ("drm: qxl:
      Don't alloc fbdev if emulation is not supported"), prevent the Oops in
      the unbind path of Bochs if fbdev emulation is disabled.
