gpio: lp873x: remove unnecessary call to platform_set_drvdata()

[PATCH] gpio: lp873x: remove unnecessary call to platform_set_drvdata()

Posted by Andrei Coardos 2 years, 6 months ago

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.

Wrong version of the patch. Use -v<X>, where <X> is a number.

There is no changelog. What has been changed? What's the difference to v1
if this is assumed v2?
