vfree frees the virtually continuous memory area starting at addr. If addr is NULL, no operation is performed. So NULL test is not needed before vfree. This was done using Coccinelle: @@ expression x; @@ -if (x != NULL) vfree(x); @@ expression x; @@ -if (x != NULL) { vfree(x); x = NULL; -} Signed-off-by:Bhaktipriya Shridhar <bhaktipriya96@gmail.com> Signed-off-by:

Replace pr_err() calls with respective dev_err() counterpart. Change is safe since pdev is not NULL, this was identified by hand.

Devm_ functions allocate memory that is released when a driver detaches. Replace pci_enable_device with the managed pcim_enable_device and remove corresponding pci_disable_device from probe and suspend functions of a pci_dev. Also, an unnecessary label has been removed by replacing it with a direct return statement. Signed-off-by:

Unnecessary pci_set_drvdata() has 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.
