      drm/atomic: If the atomic check fails, return its value first · a0ffc51e
      Maarten Lankhorst authored
      The last part of drm_atomic_check_only is testing whether we need to
      fail with -EINVAL when modeset is not allowed, but forgets to return
      the value when atomic_check() fails first.
      
      This results in -EDEADLK being replaced by -EINVAL, and the sanity
      check in drm_modeset_drop_locks kicks in:

      Solve this by adding the missing return.
      
      This is also a bugfix because we could end up rejecting updates with
      -EINVAL because of a early -EDEADLK, while if atomic_check ran to
      completion it might have downgraded the modeset to a fastset.

         - compressed boot: Ignore a generated .c file
      
         - VDSO: Fix a register clobber list
      
         - DECstation: Fix an int-handler.S CPU_DADDI_WORKAROUNDS regression
      
         - Octeon: Fix recent cleanups that cleaned away a bit too much thus
           breaking the arch side of the EDAC and USB drivers.
      
         - uasm: Fix duplicate const in "const struct foo const bar[]" which
           GCC 7.1 no longer accepts.
      
         - Fix race on setting and getting cpu_online_mask
      
         - Fix preemption issue. To do so cleanly introduce macro to get the
           size of L3 cache line.
      
         - Revert include cleanup that sometimes results in build error
      
         - MicroMIPS uses bit 0 of the PC to indicate microMIPS mode. Make
           sure this bit is set for kernel entry as well.
      
         - Prevent configuring the kernel for both microMIPS and MT. There are
           no such CPUs currently and thus the combination is unsupported and
           results in build errors.
      
        This has been sitting in linux-next for a few days and has survived
        automated testing by Imagination's test farm. No known regressions
        pending except a number of issues that crept up due to lots of people
        switching to GCC 7.1"
