Subject: [PATCH 0/6] staging: Remove unnecessary *_set_drvdata()
Date: Thu, 25 Feb 2016 11:07:14 +0530 [thread overview]
Message-ID: <cover.1456377485.git.amitoj1606@gmail.com> (raw)
Unnecessary [platform|pci|spi|dev]_set_drvdata() have been removed
since the driver core clears the driver data to NULL after device
release or on probe failure. There is no need to manually clear the
device driver data to NULL.
The Coccinelle semantic patch used to make this change is as follows:
// <smpl>
@@
struct platform_device *pdev;
@@
- platform_set_drvdata(pdev, NULL);
@@
struct pci_dev *pci;
@@
- pci_set_drvdata(pci, NULL);
@@
struct spi_device *spi;
@@
- spi_set_drvdata(spi, NULL);
@@
struct device *dev;
@@
- dev_set_drvdata(dev, NULL);
@@
struct amba_device *dev;
@@
- amba_set_drvdata(dev, NULL);
// </smpl>
