      drm/ssd130x: Silence a `dubious: x & !y` warning · 51affef3
      Javier Martinez Canillas authored
      
      
      The sparse tool complains with the following warning:
      
      $ make M=drivers/gpu/drm/solomon/ C=2
        CC [M]  drivers/gpu/drm/solomon/ssd130x.o
        CHECK   drivers/gpu/drm/solomon/ssd130x.c
      drivers/gpu/drm/solomon/ssd130x.c:363:21: warning: dubious: x & !y
      
      This seems to be a false positive in my opinion but still we can silence
      the tool while making the code easier to read. Let's also add a comment,
      to explain why the "com_seq" logical not is used rather than its value.

      fbdev: Remove unused struct fb_deferred_io .first_io field · 998101f2
      Javier Martinez Canillas authored
      This optional callback was added in the commit 1f45f9db
      
       ("fb_defio:
      add first_io callback") but it was never used by a driver. Let's remove
      it since it's unlikely that will be used after a decade that was added.
