Subject: [PATCH] serial: tegra: Use devm_platform_get_and_ioremap_resource()
References: bsc#1214683 (PREEMPT_RT prerequisite backports)
Patch-mainline: v6.6-rc1
Git-commit: f9061d3b7899e946f0db6ef7b727c40c01cfbd45
Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
