[PATCH 2/2] bus: qcom-ebi2: simplify the code in qcom_ebi2_probe()

From: Ziliang Liao
Date: Sun Apr 30 2023 - 08:54:23 EST


The code use platform_get_resource() and devm_ioremap_resource() to
allocate memory resources for the device. It can be simplified by using
devm_platform_ioremap_resource().
