Bhumika Goyal ce7e581e6b Staging: sm750fb: Remove unused functions
The functions dviGetDeviceID and dviGetVendorID are not used anywhere in
the kernel so remove them. Also, remove their function prototypes.
Grepped to find occurences.

Eva Rachel Retuya 6504b9bdf6 staging: sm750fb: convert pr_err() to dev_err()
Replace pr_err() calls with respective dev_err() counterpart.
Change is safe since pdev is not NULL, this was identified by hand.
Semantic patch used to detect and apply the transformation:

Amitoj Kaur Chawla 13b79a0d88 staging: sm750fb: Use pcim_enable_device()
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.

Amitoj Kaur Chawla fad2564eaa staging: sm750fb: Remove unnecessary pci_set_drvdata()
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.

The Coccinelle semantic patch used to make this change is as follows:

struct pci_dev *pci;
