From 11d14267de25b3eb5ff785b35152181770a82940 Mon Sep 17 00:00:00 2001 From: Subbaraman Narayanamurthy Date: Fri, 5 Feb 2021 10:08:53 +0000 Subject: [PATCH] nvmem: qcom-spmi-sdam: Fix uninitialized pdev pointer commit e2057ee29973b9741d43d3f475a6b02fb46a0e61 upstream. "sdam->pdev" is uninitialized and it is used to print error logs. Fix it. Since device pointer can be used from sdam_config, use it directly thereby removing pdev pointer.
