Subject: [PATCH] gpio: mt7621: remove unnecessary call to platfrom_set_drvdata()

This function call was found to be unnecessary as there is no equivalent
platform_get_drvdata() call to access the private data of the driver.
Also, the private data is defined in this driver, so there is no risk of
it being accessed outside of this driver file.

I have to withdraw this, the patch is wrong.
NAK.

Sorry for the confusion (I have looked for the wrong pattern).
