Dave,

Please pull this little batch of fixes intended for the 3.18 stream...

For the iwlwifi one, Emmanuel says:

"Not all the firmware know how to handle the HOT_SPOT_CMD.
Make sure that the firmware will know this command before
sending it. This avoids a firmware crash."

Along with that, Larry sends a pair of rtlwifi fixes to address some
discrepancies from moving drivers out of staging.  Larry says:

"These two patches are needed to fix a regression introduced when
driver rtl8821ae was moved from staging to the regular wireless tree."

Please let me know if there are problems!

Thanks,

John
