From: Julia Lawall <julia@xxxxxxx> request_mem_region should be used when ioremap is used subsequently. release_region is then correspondingly replaced by release_mem_region. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression start,E; @@ - request_region + request_mem_region (start,...) ... when != request_mem_region(start,...) when != start = E ioremap(start,...) @@ expression r.start; @@ - release_region + release_mem_region (start,...) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/i2c/busses/i2c-pnx.c | 7 ++++--- 1 files changed, 4 insertions(+), 3 deletions(-) diff --git a/drivers/i2c/busses/i2c-pnx.c b/drivers/i2c/busses/i2c-pnx.c index ec15cff..6ff6c20 100644 --- a/drivers/i2c/busses/i2c-pnx.c +++ b/drivers/i2c/busses/i2c-pnx.c @@ -586,7 +586,8 @@ static int __devinit i2c_pnx_probe(struct platform_device *pdev) alg_data->mif.timer.data = (unsigned long)i2c_pnx->adapter; /* Register I/O resource */ - if (!request_region(alg_data->base, I2C_PNX_REGION_SIZE, pdev->name)) { + if (!request_mem_region(alg_data->base, I2C_PNX_REGION_SIZE, + pdev->name)) { dev_err(&pdev->dev, "I/O region 0x%08x for I2C already in use.\n", alg_data->base); @@ -650,7 +651,7 @@ out_clock: out_unmap: iounmap((void *)alg_data->ioaddr); out_release: - release_region(alg_data->base, I2C_PNX_REGION_SIZE); + release_mem_region(alg_data->base, I2C_PNX_REGION_SIZE); out_drvdata: platform_set_drvdata(pdev, NULL); out: @@ -667,7 +668,7 @@ static int __devexit i2c_pnx_remove(struct platform_device *pdev) i2c_del_adapter(adap); i2c_pnx->set_clock_stop(pdev); iounmap((void *)alg_data->ioaddr); - release_region(alg_data->base, I2C_PNX_REGION_SIZE); + release_mem_region(alg_data->base, I2C_PNX_REGION_SIZE); platform_set_drvdata(pdev, NULL); return 0; -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
