No, this patch is only for BCM4312 devices, not the BCM43224 that you
have (there is no such thing as a "BCM4353" AFAIK - PCI device IDs
don't map directly to chip IDs!). Your card is an N-PHY, probably
revision 4 or 5 (you can see the revision by adding 14e4:4353 to the
list of PCI IDs in ssb, then looking for the "FOUND UNSUPPORTED PHY"
line in dmesg). We are working on N-PHYs, revisions <=2 will likely be
usable soon; rev.3 and newer will take longer, however. (It is
possible that this patch will also be needed for N-PHYs if they show
similar DMA errors to the 4312, but it is certainly not enough to get
N-PHYs to work.)
