How important is the name argument to request_mem_region?

devm_request_and_ioremap uses:

name = res->name ?: dev_name(dev);

In trying to introduce uses of devm_request_and_ioremap I thus look for 
res->name and dev_name(dev) as well as the name in the driver structure in
the platform_driver structure.  But sometimes the name is pdev->name, ie 
the name field of the argument to the probe function.  And sometimes it is 
a string that is slightly different than what is in the driver structure.

thanks,
julia
