[PATCH] Drivers:net:wireless:ti:wl1251: Fixed Sparse invalid assignment warning

[Surendra Patil]

Sparse warns about invalid assignment in
drivers/net/wireless/ti/wl1251/cmd.c:451:42: warning: invalid assignment: |=
drivers/net/wireless/ti/wl1251/cmd.c:451:42:    left side has type restricted __le16
drivers/net/wireless/ti/wl1251/cmd.c:451:42:    right side has type int
Hence type converted right side to __le16.

AFAIR wl1251 is not really endianess-safe.  I think there are lots of
other places where endianess macros should be added.

Nothing wrong with this patch, I'm just saying that while at it, maybe
someone could take care of all the endianess issues with wl1251? ;)
