Subject: [PATCH] staging: rtl8192u: fix large frame size compiler warning
Compiling drivers/staging/rtl8192u/ gives following compiler warning:
drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c: In function
‘RxReorderIndicatePacket’:
drivers/staging/rtl8192u/ieee80211/ieee80211_rx.c:758:1: warning: the
frame size of 1064 bytes is larger than 1024 bytes
[-Wframe-larger-than=]
This patch fixes it by replacing the statically allocated array
`prxbIndicateArray` with kmalloc'd one.
