Thanks for including my proposal. However, it seems as if your mailclient wraps lines and converts tabs into spaces. The patch doesn't apply. Please have a look at Documentation/email-clients.txt and check the other patches aswell. A good way to check if everything is right is to send the patchset to yourself and then try to apply it. If it works, send it to the mailing list. > --- linux-2.6.24-rc5/drivers/dma/iop-adma.c 2007-12-16 11:15:52.000000000 > +0100 This line is wrapped... > +++ linux-2.6.24-rc5/drivers/dma/iop-adma.c.cj 2007-12-19 20:44:58.000000000 > +0100 dito. > @@ -858,10 +858,10 @@ static int __devinit iop_adma_memcpy_sel > > dev_dbg(device->common.dev, "%s\n", __FUNCTION__); > > - src = kzalloc(sizeof(u8) * IOP_ADMA_TEST_SIZE, GFP_KERNEL); > + src = kmalloc(IOP_ADMA_TEST_SIZE, GFP_KERNEL); The tabs were replaced by a single tab (the same goes for the rest of the patch). > if (!src) > return -ENOMEM; > - dest = kzalloc(sizeof(u8) * IOP_ADMA_TEST_SIZE, GFP_KERNEL); > + dest = kzalloc(IOP_ADMA_TEST_SIZE, GFP_KERNEL); > if (!dest) { > kfree(src); > return -ENOMEM; > @@ -871,8 +871,6 @@ static int __devinit iop_adma_memcpy_sel > for (i = 0; i < IOP_ADMA_TEST_SIZE; i++) > ((u8 *) src)[i] = (u8)i; > > - memset(dest, 0, IOP_ADMA_TEST_SIZE); > - > /* Start copy, using first DMA channel */ > dma_chan = container_of(device->common.channels.next, > struct dma_chan, CCing the Maintainer would also increase the chance for an merge.
