      After the last "package" of firmware data is sent to the device, we dereference
      NULL pointer (on access to rec->addr). Fix it.

      [PATCH] USB: Emagic USB firmware loading fixes · 16c23f7d
      Monty 提交于
      It's become apparent as machines get faster that the emagic kernel firmware
      loaders (based on the ezusb loader) have a reset race.  a 400MHz TiBook
      never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
      time.  The bug is seen as a hung USB box and the kernel error:
      
      drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
      error = -110
      
      The patch below inserts a delay after deasserting reset to allow the box to
      settle before a new command is issued.  This affects only device startup.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
