From 036d193d3337365e0d69cff9bb2593bfc1210e7b Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Thu, 5 May 2016 19:29:49 -0500 Subject: [PATCH] regulator: tps65917/palmas: Simplify multiple dereference of ddata->palmas_matches[idx] Converting dt to platform data logic involves picking up information that is unique per regulator, however we can improve readability of the code by dereferencing ddata->palmas_matches[idx] once in the loop. While at it fix reuse of generic palmas_matches common variable while reporting error for a specific regulator (which may be from 65917/palmas list).
