Subject: [PATCH] staging: wlan-ng: Fix endianness warnings
From: Alfonso Lima Astor <alfonsolimaastor@...il.com>
These variables were set to u16 and u32 although they always hold a little
endian value.
This patch fixes multiple sparse warnings like:
drivers/staging/wlan-ng/prism2sta.c:375:46: warning: cast to restricted __le16
Signed-off-by: Alfonso Lima Astor <alfonsolimaastor@...il.com>
