minstrel_ht

Hello Thomas Huehn,

The patch 0a08adeb773c: "mac80211: correct size the argument to
kzalloc in minstrel_ht" from Jun 29, 2012, leads to the following
Sparse warning:
	net/mac80211/rc80211_minstrel_ht.c:816:33:
		warning: expression using sizeof(void)

-       msp->ratelist = kzalloc(sizeof(struct minstrel_rate) * max_rates, gfp);
+       msp->ratelist = kzalloc(sizeof(*msp->ratelist) * max_rates, gfp);
        if (!msp->ratelist)
                goto error;

"msp->ratelist" is a void pointer so that will cause memory corruption.
You could consider making it a struct minstrel_rate pointer.  I haven't
looked at this.

regards,
dan carpenter

You'll have to sent a patch which applies on top of linux-next
because your other patch was already applied.

Please don't drop the list from the CC.
