[PATCH 3/3] i2c: qup: Use devm_platform_ioremap_resource helper

[Saiyam Doshi]

platform_get_resource() and devm_ioremap_resource() together.

The semantic patch that makes this report is available
in scripts/coccinelle/api/devm_platform_ioremap_resource.cocci.

Can a wording like “Simplify this function implementation by using
a known wrapper function.” be nicer for this change description?

Can a tag like “Generated by: scripts/coccinelle/api/devm_platform_ioremap_resource.cocci”
be more helpful than the other description variant?
