SubjectRe: [PATCH 2/2] Fix endiannes error

In reply to#1591453
These patches look good but you need to resend with a correct subsystem
prefix in the subject.  It should be:

[PATCH 2/2] Staging: wlan-ng: Fix endiannes error

Hm...  Also "endiannes" doesn't look like correct spelling.  Just say
"endian".

Generally we like to put the "Compile tested only" bit under the ---
cut off so that our patches look more confident and authoritative.  ;)

Patch does not apply to my staging-next branch.  Can you rebase it and
resend?

#1596370 — [PATCH 2/2] Staging: wlan-ng: Fix endian error

FromAdrien Descamps <adrien.descamps@gmail.com>
Date2017-03-09 21:20 +0100
Subject[PATCH 2/2] Staging: wlan-ng: Fix endian error
Message-ID<tjcHv-1H0-11@gated-at.bofh.it>
In reply to#1596273
sparse report fixed:
drivers/staging//wlan-ng//hfa384x_usb.c:3517:35: warning: restricted __be64 degrades to integer
drivers/staging//wlan-ng//hfa384x_usb.c:3517:33: warning: incorrect type in assignment (different base types)
drivers/staging//wlan-ng//hfa384x_usb.c:3517:33:    expected restricted __be64 [usertype] mactime
drivers/staging//wlan-ng//hfa384x_usb.c:3517:33:    got unsigned long long

Computation on the value should be done when in machine format, not in big endian format.

Message-ID<tjcHv-1H0-13@gated-at.bofh.it>
In reply to#1596273
Fix some sparse warning by using correct endian types in structs and
local variables.
This patch only fix sparse warnings and do not change the logic.
