[PATCH] staging: rtl8192u: fix large frame size compiler warning

From: Okash Khawaja
Date: Wed Dec 16 2015 - 17:34:46 EST


This patch fixes following compiler warning:

drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c: In function
âRxReorderIndicatePacketâ:
drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c:758:1: warning: the
frame size of 1064 bytes is larger than 1024 bytes
[-Wframe-larger-than=]

It replaces the statically allocated array prxbIndicateArray with
a kmalloc'd one.
