From e5cedefa7203c787ccadaa3e2400d0b8e252a0c1 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 7 Sep 2022 13:07:24 +0200 Subject: [PATCH] phy: qcom-qmp-combo: shorten function prefixes The driver function prefix has gotten unnecessarily long and hurts readability. Shorten "qcom_qmp_phy_" to "qmp_" (which likely stands for "Qualcomm Multi PHY" or similar anyway).
