From 3667802808bec02e0762ef95a4058d17281a79a3 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Tue, 29 Oct 2019 11:42:31 +0000 Subject: [PATCH] nvmem: core: fix nvmem_cell_write inline function [ Upstream commit 9b8303fc6efa724bd6a90656434fbde2cc6ceb2c ] nvmem_cell_write's buf argument uses different types based on the configuration of CONFIG_NVMEM. The function prototype for enabled NVMEM uses 'void *' type, but the static dummy function for disabled NVMEM uses 'const char *' instead. Fix the different behaviour by always expecting a 'void *' typed buf argument.
