Subject: [PATCH] staging: rtl8192u: fix large frame size compiler warning
Date: Wed, 16 Dec 2015 21:15:34 +0000	[thread overview]
Message-ID: <20151216211534.GA13478@bytefire-computer> (raw)
In-Reply-To: <20151216205545.GA12609@bytefire-computer>

This patch fixes 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=]

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