      vfs: fix up ENOIOCTLCMD error handling · 07d106d0
      Linus Torvalds authored
      We're doing some odd things there, which already messes up various users
      (see the net/socket.c code that this removes), and it was going to add
      yet more crud to the block layer because of the incorrect error code
      translation.
      
      ENOIOCTLCMD is not an error return that should be returned to user mode
      from the "ioctl()" system call, but it should *not* be translated as
      EINVAL ("Invalid argument").  It should be translated as ENOTTY
      ("Inappropriate ioctl for device").
      
      That EINVAL confusion has apparently so permeated some code that the
      block layer actually checks for it, which is sad.  We continue to do so
      for now, but add a big comment about how wrong that is, and we should
      remove it entirely eventually.  In the meantime, this tries to keep the
      changes localized to just the EINVAL -> ENOTTY fix, and removing code
      that makes it harder to do the right thing.

      mwifiex: fix crash during simultaneous scan and connect · b015dbc0
      Amitkumar Karwar authored
      If 'iw connect' command is fired when driver is already busy in
      serving 'iw scan' command, ssid specific scan operation for connect
      is skipped. In this case cmd wait queue handler gets called with no
      command in queue (i.e. adapter->cmd_queued = NULL).
      
      This patch adds a NULL check in mwifiex_wait_queue_complete()
      routine to fix crash observed during simultaneous scan and assoc
      operations.
