Patch does not apply to my current spi/next branch[1]. [1]git://git.secretlab.ca/git/linux-2.6 spi/next While I'm thinking about it; Kevin, how do you want me handling OMAP spi patches. Do you want to pick them up, test them and send me a git branch to pull like with gpio? Or can I just pick them up? g. > > CC: grant.likely-s3s/WqlpOiPyB63q8FvJNQ@public.gmane.org > CC: tony-4v6yS6AI5VpBDgjK7y7TUQ@public.gmane.org > Signed-off-by: Hannu Heikkinen > --- > drivers/spi/spi-omap2-mcspi.c | 27 ++++++--------------------- > 1 file changed, 6 insertions(+), 21 deletions(-) > > diff --git a/drivers/spi/spi-omap2-mcspi.c b/drivers/spi/spi-omap2-mcspi.c > index bb9274c..392efce 100644 > --- a/drivers/spi/spi-omap2-mcspi.c > +++ b/drivers/spi/spi-omap2-mcspi.c > @@ -1166,17 +1166,12 @@ static int __init omap2_mcspi_probe(struct platform_device *pdev) > r->start += regs_offset; > r->end += regs_offset; > mcspi->phys = r->start; > - if (!request_mem_region(r->start, resource_size(r), > - dev_name(&pdev->dev))) { > - status = -EBUSY; > - goto free_master; > - } > > - mcspi->base = ioremap(r->start, resource_size(r)); > + mcspi->base = devm_request_and_ioremap(&pdev->dev, r); > if (!mcspi->base) { > - dev_dbg(&pdev->dev, "can't ioremap MCSPI\n"); > - status = -ENOMEM; > - goto release_region; > + dev_dbg(&pdev->dev, "can't request mem and ioremap MCSPI\n"); > + status = -ENOMEM; > + goto free_master; > } > > mcspi->dev = &pdev->dev; > @@ -1191,7 +1186,7 @@ static int __init omap2_mcspi_probe(struct platform_device *pdev) > GFP_KERNEL); > > if (mcspi->dma_channels == NULL) > - goto unmap_io; > + goto free_master; > > for (i = 0; i < master->num_chipselect; i++) { > char dma_ch_name[14]; > @@ -1241,12 +1236,8 @@ disable_pm: > pm_runtime_disable(&pdev->dev); > dma_chnl_free: > kfree(mcspi->dma_channels); > -unmap_io: > - iounmap(mcspi->base); > -release_region: > - release_mem_region(r->start, resource_size(r)); > free_master: > - kfree(master); > + spi_master_put(master); > platform_set_drvdata(pdev, NULL); > return status; > } > @@ -1256,8 +1247,6 @@ static int __exit omap2_mcspi_remove(struct platform_device *pdev) > struct spi_master *master; > struct omap2_mcspi *mcspi; > struct omap2_mcspi_dma *dma_channels; > - struct resource *r; > - void __iomem *base; > > master = dev_get_drvdata(&pdev->dev); > mcspi = spi_master_get_devdata(master); > @@ -1265,12 +1254,8 @@ static int __exit omap2_mcspi_remove(struct platform_device *pdev) > > omap2_mcspi_disable_clocks(mcspi); > pm_runtime_disable(&pdev->dev); > - r = platform_get_resource(pdev, IORESOURCE_MEM, 0); > - release_mem_region(r->start, resource_size(r)); > > - base = mcspi->base; > spi_unregister_master(master); > - iounmap(base); > kfree(dma_channels); > destroy_workqueue(mcspi->wq); > platform_set_drvdata(pdev, NULL); > -- > 1.7.10 > -- Grant Likely, B.Sc, P.Eng.
